BTEC Level 3 Extended Diploma, UNI and A levels.NEED ADVICE

I am currently doing BTEC Extended Diploma Forensics Science Level 3, I originally wished to go to either Cambridge, Oxford or another really good university in the UK to study science at professor. My GCSE's was English C, Maths C, Triple Science; Biology C, Physics C, Chemistry C. I didn't know that after I finished this course at college if I could do A level Maths, Chemistry, Physics And Biology as well as my already gained (by this time) BTEC Level 3 Diploma. I would wish to do A levels to allow myself to be able to apply to Cambridge or Oxford however with GCSE results could I or not...Hope it makes sense and advice could be given. Thanks
