And I realised I've forgotten absolutely everything I studied in Sec sch, in poly.... zzz.... Its damm jia lat... I'm still working on differentiation... not even reached integration, Log, Ln yet...... sad.... kinda like relearning everything from scratch... Without a teacher to guide some more... >.<" Wad to do, wad to do...
