How is my score calculated (using percentage weightage)?

[DarkEclipse]

So...how does it work?
For example, in French as a Foreign Language(0520),I got 42/48 in Paper 1, 58/65 in Paper 2, 93/100 in Paper 3 and 32/50 in Paper 4, and each paper carries a percentage of 25 (i.e. 25%), then what is my score on hundred?
I'd appreciate a quick reply

According to my knowledge it would be calculated something like:
(42/48)*25+(58/65)*25+(93/100)*25+(32/50)*25
Result= 83.43
Correct me if I'm wrong.
