chemistry p5

[leadingguy]

I have posted in chem doubts section but unfortunately there was no response to my questions.
the main reason I found was that the dominance of As questions and some some how a little A2 p4 questions too are asked. Where as chm p5 is also tough and needs special attention.
I am making the thread with the wish that thsoe A2 guys who are currently practicing p5 can easily help me.
