For 2nd PUC (Pre-University Course) quarterly test papers in Bangalore South, the best sources are your college’s academic office, your subject teachers, and the Karnataka Department of Pre-University Education website. Many PU colleges share previous quarterly and mid-term papers with students for practice, so request copies from your seniors too. If you can’t get the exact Bangalore South set, practicing any Karnataka 2nd PUC quarterly paper from the same academic year will help because the syllabus and question styles are almost identical. Solving these papers not only improves your speed but also gives you a realistic idea of marking schemes. I also recommend writing answers in exam-like conditions to get used to time pressure.

Good luck for your tests, and thanks for your question!
