Dear Student,

You could always refer to the previous years paper and get an idea of how the papers are set. Which questions are repeated again and again. So you have a chance that it could get repeated again.

Chemistry is not just about organic ( ie. Reaction  it has more 2 branches physical and inorganic.

You could always try and sort out what you can study well and give priority to that branch but make sure you are interested and ready to give it your 100%.

Another way is try to focus of marks alloted to chapters don't dump the chapters that have low marks allocated. This are the scoring places were direct questions appear.

If you want to study the full portion for good marks, first cover up the topics that you are comfortable with, make sure you are 100% with it. Than go for the topics you find important and you have skipped out. Last go to the part you find difficult try to use help from youtube videos or simply ask your teaches or friends. But make sure you notes are up to the mark first of all
