Hi,
I am Dr. Prerna. For Q bank and test series i will suggest you to go for Marrow without any doubt. I am using it from few months. it have increased my confidence. Their content are made by top rankers and subject specialist doctors. Not only this they also helps us with our queries if we have any doubt in any question. They have a feature called pearl which is the best way for revising important topics in last minute and it makes important points easy to memorise by the beautiful way they have designed it. You can try the free Q bank chapters before you take subscription.I am sure you will like it. All the best.
