Wow, I can't believe this hit the front page! Its past midnight here in the UK and I have to be up early for GCSEs, so I'm heading to sleep. I'll read and reply to all your comments and questions first thing in the morning! Thank you all so much for the amazing feedback and stars so far.
You're gonna smash it. Regardless of what your GCSE results are, stuff like this is what will take you far in life. All the best for your exams, but don't lose any sleep over them either.
Best of luck to you! My son is doing them too. This is a great project btw. Doing this sort of stuff teaches you far better than endless lessons.
