does errorless physics covers all the topics of neet ug physics

Jayanth, we understand that you want to appear for NEET 2021. Now the Union Minister of HRD has announced that NEET 2021 will be conducted on a reduced syllabus. But the reduced syllabus has not been released yet. Every year NTA releases its online notification for NEET tentatively in the month of December. It might be around the same time that NEET syllabus also might be announced. Now you do not need to cover all the topics because certainly few will be ommitted. And you purchasing Errorless Physics might be we wouldnt call it waste of money but it might be redirecting your energy into additional syllabus while you could have utilised the same time to concentrate on other subjects. If NTA releases the Syllabus in December and hopefully NEET 2021 is conducted in May, you should have enough time to purchase any book that is relevant to that syllabus. Until then focussing on NCERT books will be a wise move. Following what is taught in the school and practising them without fail and memorising the concepts and formulae should help you keep yourself upto date when it comes to preparation for NEET. The same goes with Biology and Chemistry too. Did you know that 98% of the questions are asked from NCERT alone and the rest 2% questions are asked from other books. So 5 months is a good time to prepare for the rest 2% of the questions. But to answer your question, Errorless Physics has approximately 1563 Pages. So it covers all the topics for NEET Physics until 2020. It has not been updated according to 2021 syllabus yet because the new reduced syllabus is yet to be known.
