My history topics are crime and punishment, nazi Germany, cold war and Henry & his ministers. Although History is my current least favourite subject
I'm just not interested in it.
Computer science is very good if you're interested in, you know... computers. I like it as it gives me answers to questions about computers that I have never asked and it fascinates me how it all works. Would recommend!
I'd love to also hear how you're revising too as I am also learning about this whole revision thing. Good luck to you too!
