The subjective part is ok when you read organic chemistry but one should alway remember the vastness of the subject and the way various questions can be touted from a very single topic. Hence it utmost mandatory and wise to not only study theory, but also practice as many MCQs as possible, starting with Medical Levels and slowly proceeding to cover some parts of Engineering too for NEET.

For AIIMS, you need a higher conception and so engineering level is recommended.

Aakash itutor although good may at times shall not be able to clear doubts and answer retrospect questions, hence it is also good to have a partner or a guide to better understand Organic Chemistry.
