Oneshots or nah?

Basically left with 12th portion of syllabus for ray optics, wave optics, magnetism, semi conductors. Rest I have done in detail so I can just revise and solve mcqs to get the same master.

Merah batch around March end meh khatam ho rha hai. Which is fucked since I wanna complete syllabus by Feb end (with 80% revision and questions practice)

People have told meh ache detailed chaps hai yeh sb detailed seh karu but I don't think there's enough time left. Personally need you guy's opinion if I'm kicking myself in the balls by switching to oneshots.

However if you have good teacher eccos for oneshots please do share them.
