Struggling with Maths: PYQs or Mathongo Premium DPPs for Quality Practice? Need Advice!

Physics and Chemistry are decent, but Maths is a mess. I’ve done some chapters but barely practiced, and I still have backlogs in Calculus, Probability, and PnC. I would complete these chapters from youtube oneshots. I need good-quality questions to practice but have limited time. I’ve got Mathongo Premium DPPs, but should I focus on those or PYQs? **Anyone who’s done both, please share what worked for you!**
