Maths test tomorrow.

I just found out that around 70% in maths is a 7. So I'm aiming for about 60-70% in the test tomorrow. IB is so different from year 10, I no longer have to aim for 90% in my tests because the percentage for a 7 is different in all my subjects. Especially higher maths, which is so hard that they made the cut off line for full marks only a B. I'm praying for good marks in maths.
