Hi.
The preparation of NEET is usually a long drawn out, painstaking process that requires ample amount of time for you to not only prepare once but also revise.
However, since you have a paucity of time, crash courses in various institutes that provide entrance exam coaching should be a good option. You will probably have to slog for most of the day in the 2 months you have to be able to cover a sizable amount of course content. Also it is advisable that you solve the previous year papers thoroughly.
Stay focused and work hard! Good luck.
