Worried I won't get in - Help!

So by March you are hoping to have:

Maths: A
Psychology: B
Economics: A/B
Further Maths: a/b

And I assume you'd then take the rest of your Further maths exams in June and get the results for them in August: So in August you'd actually have Four full A levels? Maybe AAAB or AABB?

You could easily get into a top uni with those. (Including Warwick perhaps)

You can't change your options in March, the unis you apply to in November are your official applications and by march they will have already given you offers!

You don't need to "explain the situation" - You can put a sentence or so in your Personal statement if you really want to, or your teacher would explain in their reference on your UCAS form. You'd simply apply with Maths A, Psychology B, and your Economics and Further maths grades pending but predicted A/B from your teacher.

Alternatively, you could take a year out (to work or get work experience, or travel etc) and apply with AAAB/AABB after you've achieved everything. If you feel it'd improve your chances.

Yes thankyou.

I am confident of meeting conditional offers of say AAAB or AABB but just worried I won't be given a chance because of doing it over three years, and only having two A2 levels when applying...

I think you should arrange to sit down and have a chat with your tutor (whoever does your UCAS form at school) and ask about what grades you are predicted and whether its worth mentioning why they were done over three years, and if it is, whether you put it in your PS or whether your teacher will take care of it in their reference.

I don't think that doing them over three years will hurt your application at all, and even if it did, that would easily be overridden by the impressive fact that you taught yourself Further Maths!

Think of it this way: when most people apply, they have NO A levels! Just predicted grades! So only having two won't be a disadvantage to you, you are fine!
