Do I stand a chance of getting into The University of Cambridge for Maths/Mechanical Engineering?

I do not have any knowledge of Cambridge as I am in Scotland but here to get an acceptance for any university degrees your will also need A-Level English as the 3 main requirements in GCSE & A-Levels is English, Maths & Science subject. Or here in Scotland it is Standard Grades and Highers. You have done well in your GCSE and I hope you get the requirements in your A-Levels and I wish you all the best. Good Luck.
