Hmm ... during my batch (2005), one of the teachers told us thru
the examiner's report that the A1 grade is placed at 93 raw score
for E Maths and 85 raw for A Maths. Talk about that.
I must say E Maths is a relatively straightforward subject, but it
places emphasis on accuracy more than others, but for A Maths you
need lots of practice to sharpen your tricks.
