well, being predicted an a* is always a good start i guess.
i got taught as maths and f maths in 10 lessons a week, so i dont know if you may be disadvantaged with 8 lessons
if your teachers are competant enough to teach it well, and you find the exercises from the book alrite, then you should be fine
it's a tough subject to be fair, but not impossible to do, and get an A in
