I am cooked

Okay so I have wasted my 11th till now. In the start I was preparing for an entrance exam, which took all of my April and May. I did crack it tho, but my main focus now is JEE. I have joined the Allen Online batch which started on May 28th....till now in physics we have completed units and dimensions, vectors, kinematics, will be starting with NLM soon. In chemistry we are done with moles and atomic structure. And in maths we are done with sets, fundamentals of algebra, quadratic going on rn. I really wish to restart everything from the very beginning but I need to keep up with the pace as well. Can anyone please suggest me ways to cope up with this backlog as soon as possible so that I can revert to taking live online classes. I am definitely not COMPLETELY new to the syllabus, I did prepare school level for my 40 marks unit tests that are going rn. They end on 17th and I would really like to get back in track and catch up till atleast 25. We have modules+race questions.

Thank you to anyone who helps
