Hii,I would suggest physical chemistry. Reason being, it is much more logical and less mugging required. Whenever Studying, the logical part should be prepared from starting and should be given more preference as these things wont develop over a night. They will require time. [Surface chem, Solutions and solid states are exception and should be done at the last]Followed by GOC, isomerism,functional groups and acids; i.e. most of the logical and interesting part of Organic.

Now is the time for ‘Salt Analysis’ in Inorganic Chem. Quite a bit of mugging is required but it will start making good sense when rest topics are done.

And now just sum up the rest.

Some tips- *Dont just leave the completed topics aside. Regularly practice on them. Do some weekly questions to keep them fresh. *Coordinate the physics thermodynamics with that of Chem(do the phy part first tho). *The logic part applies to other subjects too. Maths as a topic cant be completed in the end-time. Try making the conceptual part strong from the start or it will haunt you!
