I think there will be quite a number of overlapping in ur calculation XD

hahaha... nice... but still u will regret if you failed your school... trust me it sucks to failed i've failed so many times and now i regretted... better manage your time properly and study before its too late...

It's just a rough estimation. It wont be true right? If it does, thn there is no such thing as school liao, since we have no time.
If u fail ur module, this calculation is good to make as an excuse to ur parents.lol
