A2A,
There are three subject and I used to study all of them in rotation pattern per day along with question practice.
However it is not necessary to read all subject per day.you can read physics all day or chemistry or biology but according to me after reading same subject for long time,our efficiency may decrease.
Complete your Minor tests syllabus on time and never ignore any topic because you know 600/720 is a tough task.
Question practice is essential on daily basis and constancy is the key of success in any competitive entrance.
The secret to success is constancy of purpose…
