is reading line by line NCERT for physics is mandatory ??
NCERT is the holy grail. We have always heard this. But when it comes to subjects like physics and chemistry, students tend to ask this question because they are already left with little time in their preparation. However, this saying that NCERT must not be left is true because after all it is the prescribed text and even tge more difficult books move forward from the concept of the NCERT. Conclusively you must read it well at least once.
