Nothing is enough unless the aspirant itself sweats down for the NEET PG.
Only watching videos and doing some Q models with a few tests attended won’t give success.
One needs to religiously follow and get a rough plan month wise or divided months before the provided date of main exams.
Many aspirants plan to first watch ALL videos and read ALL notes before attending a single test or solving q banks. This is quite common with many Marrowlings with plan C. They lose track in between and later find themselves in difficult situation.
Preparation from Marrow keeps one busy but I suggest that since it’s a new experience and as we see many top rankers having more than one type of instt for preparing, Along with plan C attend a TnD session from your nearest Coaching ( Bhatia/Dams/any other good one).
Second option Is Just take plan B and join for Revision classes in such instt.
Marrow suggests that it saves your time by allowing you to prepare from your device with good internet at any place of your choice. This may make many prone to laziness within months.
Plan C is better with Marrow modifying itself as per time demands. However, one can’t take chance and it’s better to devote time judiciously.
Remember, after all every teacher suggest for a well crafted Revision plan till the end. According to your time plan choose wisely.
