Hi,

Need your advice. I'm weak in chemical calculations. Any tips on how to improve?

Perhaps part of the tips would be to master chemical formulas and balancing of chemical reactions since those are essential factors in chemical calculations.

Wish my parents are as supportive as you. There are just times when students really need help and guidance especially when we are overwhelmed by the stuffs we need to catch up.
