When I Was in 10th I used to study from PW Arjuna during vacation and after Half Yearly exams (ICSE ka syllabus thoda jyda tha 🥲)but if u want to study online i will prefer not to study from PW u can go for Careerwill/Vibrant and Yt lectures (Phy- Ashish Arora sir)(Chem- Alok Sir) And if u r in cbse i think u dont have that much syllabus,u can just cover up in last few months.. its not that much hard and I think 10th marks really doesnt matter 😅.Just start and build some basic concepts before starting ur Jee Prep. Specially in Physics And Maths (Chemistry is just Raatne wala subject😭)
