Avanti videos are great, concise and easy to understand also I like how they discuss problems in the videos step by step.These help me to revise old topics as well understand new ones. I solve the Avanti workbooks topic wise and also the solutions are also well explained. I am satisfied with the quality and quantity of questions in the modules also telling the students the level of each and every question is very useful for us. Doubt solving is awesome and I am satisfied with the efforts put in by my mentor for helping me in solving problems as well as real life problems. I would definitely recommend Avanti to my friends.
