I've officially finished exam season, with ease, I might add (if you exclude the breakdowns), I'll have the scores on July 3rd, but here's an estimate:
Highest possible Expecting
Polish* - 95% (2 mistakes) 85%
Maths - 97% (1 mistake) 90%
English - 100% 98%
* - Polish depens on how they grade my essay, maths depends on how they'll grade one particular exercise, English depends on an email, which I will realistically ace.
