Year 12s: what will be the first way you research your future options? >>

Do I stand a chance?

Im currently an A2 student doing Biology, Chemistry and physics. Due to medical issues I missed almost 4 months of school before and after the January 2013 exams which resulted in me getting 3 U grades for my A2 units. I now have 6 exams in the summer which I don't know anything about and I am considering withdrawing myself from them and applying for dentistry with my predications of 3 A*s from my AS ums marks which were 283, 273 and 279.

I then plan on sitting my A2 modules for the first time next June. Would I be considered as a retake candidate by Sheffield and Leeds and would I be at a big disadvantage?
