So I'm aiming for a Cambridge education in engineering. I have 8 A*s 2 As (+A^ FM) at GCSE. I'm doing Maths Further Maths Physics and Chemistry, all of which I'm finding pretty manageable. I'm taking part in the EDT Engineering Education Scheme (in school curriculum). Also I try and do as much work experience as I can, although not all of it has been to do with engineering.
What else can I do to increase my chances of going to Cambridge? I've heard of the STEP papers, but I'm aware they are only required for a few select colleges; would it be helpful if I did some of them anyway? I've also applied for an EDT Headstart taster course for engineering at cambridge, but I havnt heard back yet; would this be useful, my school is against me going as it is in school time. What other things should I be doing to increase my odds at getting a place in Cambridge? I don't mean to be naive, but I feel like that's the kind of university I belong at; although I havent always been a hard worker (for my GCSEs i didnt revise for more than a month), I feel mentally strong and capable.
Thanks for the help!
