Also, if I get A+ in both the exams, and I have full marks in all my sacs, will that mean about a 49 for me? Even if I lose marks in the exams?
Nope, to get a 50, you're looking at losing basically 1 mark maximum if this year goes pretty poorly on the exams, considering an A+ in exam 1 last year was 36/40, Getting A+'s in both exams, won't guarantee a 49-50.
Last Year girl got 50 at our school losing one mark in second exam.
Which reinforces what I said, that you can only lose a maximum of 1 mark. From rebeckab's wording, asking that if she got an A+ (any score that gets her an A+), will she be guaranteed a 49-50, in which case I said no, due to the cut offs for A+'s potentially being around 36, resulting in a maximum of 4 lost marks in 1 exam alone.
