So with these subjects:
std eng
gen maths
pe
ipt
bio
with a school of rank more than 150, e.g. rank 190
getting top 10 in these subjects will give me an estimate of?
If your ranked 10th in all these subjects with a school rank of 190 I would say maybe around 78-80. Ipt and pdhpe would need to be worked on. And standard English doesn't help.
