A Level Problem Very Important !

ok I had to attract people some how, thus the psycho title

I want to calculate my final grade by the end of A2 (as in all the grades (IGCSE + AS + A2)). How do I get the grade?

What is the weighting of each level?

Example (NOT REAL example ):
A2 counts as 45 percent of the final grade.
AS counts as 25 percent of the final grade.
IGCSE counts as 30 percent of the final grade.

Whats the real weighting ?

Thanks !

Aren't IGCSEs completely independent of A-levels, as in they don't count towards your final A-level grade? In that case IGCSE would be 0%.

AS and A2 both normally count 50% each towards your final grade. Correct me if I'm wrong though.

Yes they are independent but when I want to show universities my results I'm pretty sure my IGCSE's would have an impact on whether they will accept me or not.
The question is how much impact exactly.

IGCSE is a level 2 qualification.
A Levels are level 3 qualifications, and are made up of 50% AS and 50% A2.

So each level of qualification will be looked at seperately ?

When you apply to a university, they will only see your AS Levels.

That would be extremely devistating. I didn't do as required in my AS examinations and I will need to improve greatly in the following A2 year

I need a scholarship and I don't think I would obtain one with my AS results, so will they wait until my A2 results come out or will they totally ignore me
