Howany questions should I solve in each subject in study room. Should I solve till I reach cracku badge or anything else??

Hi, don't solve questions randomly. Make a structured plan with short term goals. For example: watch a concept video and give a concept test immediately after the video. After that, go to the study room and solve at least 40-50 questions from the study room. After completing this for every concept. Just go crazy on study room practice. Solve as many questions as you can from all the topics, try to solve at least 200+ questions from every topic.
