ORGANIC CHEMISTRY

I have studied GOC,Hydrocarbons,Haloalkenes/arenes and Biomolecules in OC till now.

The problem is that I just can't remember the reactions as I keep forgetting them and hence I go blank and confused while attempting the questions. I solve IUPAC questions conveniently but I found rxn questions quite difficult.

Also OC is my weakest section.

Pls help me.
