They QBank is concise with crisp explanations. In their Live sessions, Marrow faculty like Dr Rohan and Dr Deepu strongly suggest to completely solve QBank. The toppers mention in their interviews that they have solved 80-90% of the QBank. However, I felt that Ortho is a bit too difficult for the NEET PG exam standard, and Psychiatry as well. But all other subjects are must do. Bookmark option is great for revision.Coming to Marrow Mock Tests- Many of these toppers say in their interviews, they are very similar to the real exam.The third component is video classes - trust me, they have the best faculty! Medicine classes are a bit long, but Rakesh sir makes it very interesting that you can just keep watching. But you have to start early. Dr Abbas Ali and Dr Rohan Khandelwal are the other superstar teachers. All the teachers are the best faculty in the NEET PG field.
