Hii,Shantanu,

Firstly I would like to tell you they don't have T and D sessions. However, Marrow Tests have answers with detailed explanations and standard textbook references.But one thing according to other students review who successfully completed in Marrow I wowld to like to tell you a lot of research and learning has preceded the development of Marrow, which enabled it to create an approach best suited for the latest NEET PG pattern. Traditional coaching institutes do not adapt their teaching approach quickly.As they are not limited to a single city, they can afford to bring together the best teachers from all over India on a single platform. They also have the digital advantage, which let you provide with a personalized accurate performance analysis and improvement plans.The daily notifications sent by Marrow are a reminder for you to not skip important topics. You can make a note of them and do it according to your schedule & last one It is practically impossible for their faculty to respond to doubts by all of their users. If you have a specific feedback about an MCQ or a slide in the video lectures, you can use the feedback/report button to send across your feedback. If the feedback is relevant you will get an email from Marrow faculty. Most Marrow faculty has active Facebook pages or accounts where they clear students’ doubts.However, faculty will not be able to reply to general doubts raised via Marrow support or other channels.However, I suggest you not to spend too much time on videos or coaching. Practising MCQs on QBank is important.Best of luck..
