guesstimation help??

[Aurelie.]

Soo, I need some help with a guess of my study scores going into the exams, and what enter i may be looking at.

English- 90/100 (and on 2 practice exams, I got 91% and 94%)
History Revs- 44.5/50 + 45/50 = 89.5/100
Political Studies- 46/50 + 43/50 = 89/100
Psych- 44.5/50 + 46/50 = 90.5/100
Art- 30/30 (prac folio) + 25/50 (theory) = 93.75/100

Japanese- I got a 32 last year, which could be scaled to between 40-42

Can anyone help?
