What is everyone getting when they do past papers? I fluctuate a lot One time I got a high A and then the last attempt I got a high C. You really have to read the question carefully to understand what they mean.

Also, the markscheme changes year to year so it is really hard to know if you are writing the correct answer.

a register is a small piece of memory built into the cpu a bit like a buffer, registers are the quickest way for a system to manipulate the data, they are used to store data temporarily during the time when a program is being executed, i think im right.

I'm finder unit 2 a lot harder than unit 1 as well. What doesn't help is that (generally) the grade boundaries for unit 2 are higher than unit 1.

This book is really good, I would recommend it. They also have another for F452.

How are you guys preparing for Unit 2 though, I am really worried about that. My teacher has taught me no programming at all. I do know the basics of Java however, but can any of you guys lead me to some good tutorials or something, I would really appreciate it!

Thanks
