If I joined a dropper batch (Yakeen 2.0) right now but I haven't done my 11th from PW. Can I understand?

So I haven't done my 11th from PW and 12th I didn't my Biology and Physical and Half of organic chemistry from PW batch and had to switch to YouTube to complete the rest of chemistry because of my school exams and completed physics from offline tuition. Now if I join PW YAKEEN 2.0 batch (dropper) this year gonna be my first drop. Can I understand them? Will that be a problem? Please help a friend here guys.
