Even if one has done their graduation and post-graduation from business or arts, there is no harm but loads of benefits of learning modern soft technologies. For these, CS50 courses offered by Harvard and instructed by some highly talented and experts instructor of this institution, one will get into another level of knowledge.

Moreover, those individual courses covering a different areas of Computer Science are well organized. One will learn and can implement those in real life for their personal benefits as well as organizational benefits.

Including extremely basic which is Understanding the Technology, one can learn Programming from Scratch. In the core courses, they offer Programming with Python, CS for Lawyers, and professional Business. In the advance or follow-up courses, we will have AI, web development, and game development.

Furthermore, one will have an intense discussion below which I have written out of my personal experience on the courses.

Harvard Cs50 Course

Imagine the world ten years back, now, and after ten years. What are the changes that clicked your mind the most? Technology, right? If we think about the scenario of the world’s past, present, and future, we can realize how fast technology is growing and how impactful it is. Mainly, the department of computer science and things related to this are intense.

We can feel the presence of this science in almost every sector of our life. Whether we are working in a bank as an accountant or preparing a serious case in the law farm or even in the operation theater we will have to take help from this specific field.

The modern world is so much driving the computer science field such as programming, web, AI, Gaming, and so on. In every profession, basic knowledge of using these tools can improvise their professional life. For example, a lawyer can develop and maintain a website according to his or her law farm including all the necessary information. So that the clients can find useful information before contacting them. Also, they can use different case study software to make their work easier.

Sometimes people who graduated in Business want to pursue their career in web or android development. They feel more interested in technology than business. In that stage of life getting another 3 to 4 years of degree is quite hard. However, different introductions or basic online or offline courses can help them with their plans. Such as the Harvard CS50 Courses with an organized syllabus and focused area.

It is not an unknown fact that Harvard is one of the best educational institutes in the world. According to Times Higher Education, this university ranked 2nd worldwide and 1st nationally. Moreover, the faculties of this institute get highly appreciated for their contribution to world education, research, and discoveries. So, one can predict how wonderful, organized, and helpful it will be.

Starting from the root, Harvard introduced the first virtual office hour for CS50 back in 2007 and they launched it in Edx in 2012 which is an online learning platform. David J Malan, Professor of the Practice of Computer Science in the School of Engineering and Applied Sciences at Harvard University. He is one of the most enthusiastic and amazing faculty of this department with a broad vision for the future of the students.

According to ACM digital library, he is one of the most resourceful people with vast of useful research, citation, and whatnot.  After launching this course, it becomes the biggest course at Harvard University with more than 800 classroom students and thousands of online students.

Prof. Dr. David J Malan

One of the best things about this course is, that it is open to people of all age groups, educational statuses, and regions. One can be enrolled in almost every course for free and can learn through different platforms like Edx and YouTube. Also, they can earn a certificate after passing the exams and use it in their resume and LinkedIn profile to create their portfolio to look more professional. Moreover, let’s know about this extraordinary opportunity in detail and in-depth. After reading the whole discussion, one will know all the pros and cons as well as they can decide whether it will be a good idea to take the course. We will be discussing and illustrating in the depth all the courses out on our personal experiences.

Recently, this career-changing opportunity has 10 different courses of different levels. One can enroll in any of those at any time. There is no requirement that one has to go through this or pass that course to go to that level. It is completely the choice of the students or the learners. However, they divided those courses into three different categories. Now, we will be learning about courses A to Z.

Basic Courses

The authorities or the responsible bodies of CS50 are the most talented person. So, when they are organizing something they think of things that we cannot. Out of their concern, they have organized all the courses in categories. The basic courses are the first category and are for the very beginners. For learners who are not from Computer Sciences (CS) background and are feeling a little less confident, these courses are best for them. They can get prepared for the core and advanced courses at this level.

Understanding Technology

As stated in the official course, this is for those who do not yet consider themselves ready for core learning. It will help them understand the basics of technology from the beginning. It will make them understand the technology they use every single day but never realized it. Completing this course will make them confident for the next steps and make them interested to learn more. Specifically, they will learn,

1. Hardware

Hardware in Understanding Technology Course
The class of Hardware in Understanding Technology Course

What is the use of the internet, software, apps, and everything untouchable if there is no hardware? Before going deep into the technology one needs to understand every hardware involved like RAM, Hard Disk, CPU, and others which are covered by this class.

2. Internet

Almost one-hour discussion covers all the details of the internet. From home network breakdown to IP, DNS, and end with watching a demo of Home Router.

3. Multimedia

He starts the class with digital audio and how it works in the digital world. After that, he turned to RGB, and graphics and explain every digital operation on an image a beginner should know. He ended the lecture with a digital video and different quality performance in it.

4. Security

In this technology-based world, the thing which is in constant threat is the privacy of people’s personal data. The dishonest personalities can easily steal data like personal and sensitive information like photos, Bank information, etc. The professor will explain the threat and the measures to take to ensure the highest security on the internet.

5. Web Development

More than 60 minutes long lecture starts by explaining what web development is, also the relation of it with the internet. In the total lecture, he covers HTTP, HTTPS, HTML, Linking, CSS, and google domains. With this lecture, one will have a complete idea of the web, its development, and its use.

6. Programming

Programming class
Programming, the last lecture in Understanding Technology Course

He starts by explaining programming with Oscar time and explains a different topic related to programming. Describing pseudocode and C he entered into more deep programming languages. Meantime, he tries to make sense of loops, Functions, conditions, and many more things. Finally, explaining Python and ruby he adds some examples and ends the lecture with an ending thought.

The instructor is none other than our wonderful David J Malan and his awesome personality. With the energetic and active way of teaching with loads of real-life examples, the learners feel excited every single second of their class. He makes the little tiny soul of interest in learning in every student a bigger one. He starts with basic hardware of Computer and discusses many things in 2 to 6 hours per week lessons for 6 weeks. Finally, he ends the lectures with the basics of coding so that the students feel interested in the next level.

To complete the whole course one will need 42 days in total and every individual topic will have a different time frame. After completing the lessons one may have to take some assessment to prove that they have successfully completed the course. They will be granted a free certificate after passing the assessment. Also, one can apply for a paid and more verified professional certificate from Edx.

Introduction to Programming with Scratch

The aim of this course is to introduce a new fun programming method that does not involve text. Discovered in MIT’s LAB, one can write code by dragging and placing different graphical blocks which is a kind of puzzle. The prior student can make their own animations, games, interactive art, and stories to make projects and assignments for their study without having deep programming knowledge.

This is one of the most amazing and extraordinary courses of this CS50 project at Harvard. During the session, one will be interacting with Brian Yu, Senior Preceptor in Computer Science, Harvard University

Mr. Brian Yu
Mr. Brian Yu taking CS50’s Introduction to Programming with Scratch classes

This course includes lectures of,

1. Introduction

This is one short description of how the system will work and how can one work in making their projects. They can learn to make things like videos from the scratches here.

2. Functions

This lecture will teach different functions of the world-famous open-source programming platform. This is mainly created for children but adults can also enjoy and make the different projects. Here, they will learn how to do following some instructions. Such as, moving the avatar to a different angle and giving some voice.

3. Events

The 3rd lecture of this course is the event where the instructor makes a conversation between two avatars. Using different tools like the flag or clicking on a key in the system he shows how to create something meaningful.

4. Values

Creating values that hold information about the sprites, this lecturer covers timing, walking, and other values to make the project more alive.

5. Conditions

In this 5thlecture, we learned how to program the spirit to take decisions based on an answer to a question. For example, if I make something of an event between two Persons on a day of snowfall, one will ask if it is snowing outside. If the answer is yes, they will take the decision of wearing snowshoes and jackets.

6. Loops

All the work we have done above is just for one event. But the aim of this project is to make a meaningful film or game. Here, Loop is the function we need to make that happen. Using the loop, we do not have to press the flag or the green button again and again to run the program or code. It will repeat the command as we programmed it.

7. Variables

variables in the last class of the course
Teaching the use of variables in the last class of the course

When we make a big program we need to store different information in separate places to use it properly. In that case, we have to use a variable to store all the information to use those in our program. At the end of the course, one can make a complete video or game. The use of Scratch and using graphical blocks for programming is a wonderful way. It will teach the basics of programming to children as well as to adults who are new to this world. They will understand how the logic works inside a code.

Time table of CS50's
Time table of CS50’s Introduction to Programming with Scratch

The whole course is 2 to 6 hours which will take 3 weeks to end. Meantime, the students will be learning and submitting their works in the portal to prove their learnings. After successfully completing the course they will get a free certificate from Harvard and they can have a certified official certificate from Edx.

Core Courses

The main course or we can say the heart of this CS50 is this core course. Including that there are two more courses. Learners are excited about this part more than others because of the structure. Mainly, the students familiar with computer science choose this area or after completing the basic one, they feel interested to learn more and decided to go through the all opportunities one by one. In this section, we will demonstrate all the main genres in detail.

Introduction to Computer Science

The main instructor of this program is David J Malan. He will teach the basics of CS from scratch to core. It is suitable for major or non-major as well as with or without prior programming. Since he will cover the topic from an introductory level, everyone will enjoy and can cope with the lessons. After completing all the lectures properly, the students will have,

> A strong knowledge of CS and programming

>They will be able to think about the algorithm and how to write a code for that algorithm.

> Will gain robust concepts in different parts of computer science like data structure, array, numbers, security, and so on.

> Introduced with various languages like C, Python, JavaScript, CSS, and more.

>Finally, they can make projects out of their learnings.

I myself am a student of Computer Science and Engineering. I took this course back in 2020 when I already know so much about Computer Science and programming. However, the intense lectures of Dr. Malan have left a great impact on my head. I had learned to see this field with a fresh view. I like how he moves the primary focus from coding to thinking about the structure of each problem. One can truly implement those knowledge-solving problems in real-time. Moreover, the readers can watch the instruction to prepare for a technical interview organized by Harvard for the CS50 learners.

This is one of the longest courses with the longest lecture time of 11 weeks and 10 to 20 hours per week.

longest lecture time

After completing the lectures and during the time one will have to do a bunch of assignments. After that, they will have to perform a mock test as well as a project to gain a certificate.

Introduction to Programming with Python

The newest, released in April 2020 but the most intense course of the CS50 program is the introductory lessons of Python. We all know that python is one of the most popular and widely used programming languages in recent times. Because of the simplicity and the variation of use, people are now more interested in Python in every sector.

David J Malan will interestingly explain from scratch too deep of this language and how to start with it. Learners will know how to read, write, test, and debug their code by the end of the session. They will learn,

Git is a tool that we need to use. Then we will be learning Python and its Framework Django for doing some advanced work on websites related to data. For more, SQL, Models, and Migrations are explained in detail.

Web Programming with Python and JavaScript

After doing the main part, now it is time to think about UI and UX where we will need JavaScript to make the website more interactive and user-friendly. He ends the course by teaching and testing the codes and ensuring the security of the data as well as the website.

Overall, it will take 12 weeks to complete the course and one can earn a certificate by completing all the tasks. Moreover, they will need to give 6 to 9 hours for each lecture to complete properly. If there is a project involved, it may take more time. The time of each lecture will be like the CS50 introduction to computer Science or Python.

Mobile App Development with React Native

Another advanced and professional course is offered in the CS50. If one is already learned or passed some of the above courses like CS50 core, CS50P, and CS50W, they will find this course easier and faster to learn. The instructor of this amazing course is Jordan Hayashi, a software engineer.
