In the era of 2020 it is very easy to learn something new, to gather knowledge from worlwide resources simply sitting in your own home.
Learning out of the box is very very important for now. Even many people are curious also. For instance in the past if anyone wants to be familiar with programming he must have a fight. But now one can master codes of programming, programming languages java,c++, python through online courses only.
There are hundreds of websites which offer online courses with a variety of subjects, topics, life skills and so on.
Coursera is one of the best of them. Edx, udemy are also some example.
Coursera is best one because here instructors are only from leading universities worlwide (e.g. harvard university, duke university, cambridge university etc.) and from best companies like google, IBM etc.
Another fact is that it provides courses free of cost. You can get access to all study materials but if you want certificate you have to lose your pocket. But there is also a solution.....
