Hello candidate,

As mentioned that you have not covered specific amount of portion of your class 11th syllabus, so the first thing which you need to do is to not repeat the same mistake in class 12 and first focus on class 12 syllabus.

Secondly, you should also practice at least some of the most important chapters of class 11th which to have a correlation with most of the topics of class 12th such as general organic chemistry, isomerism, equilibrium structure, chemical bonding and atomic structure.

Hope you found it helpful!!
