Question

what basics do i need to do computer science ?

Answer 1

You just need a mediocre computer and a way of taking notes optionally. I'm using a $200 refurbished Dell laptop for writing code and good old pen and paper for notes. MIT 6.00SC uses Python which is open source and available on Mac, Windows and Linux. You will probably need Adobe Flash Player for the lectures.

Answer 2

Also, you need to have math skills, the math learned in high school should be enough to start.

Answer 3

You can ever write down the code in notes and execute it inside your mind. Fact is you only need is imagination, creativity and wishes for learning. And of course, love computer science.
