Hey hi guys. I have taken up mba wallah as coaching for cat 26. I have finished two lectures of percentage however I'm struggling with DPPs. Unable to solve a single question on my own. I either need a headstart from the video solution or getting stuck in between. Once I get the gist I'm able to solve the rest of the question. Is it bad?

For record I've been weak in maths from childhood and last time I actively studied maths was in 10th std. What do I do?
