Hii aspirant..

Studying regularly can never be two months study that a student do. If you want to pass class 12th PCM with flying colours then I would suggest you to study regularly. You should try to clear all your Basic concept of Physics, Maths and Chemistry and should try our best to get good marks.

For Chemistry NCERT is is enough you can expect to get 95 Plus in Chemistry by studying NCERT thoroughly. 

For mathematics solve as much as you can and first of all complete the NCERT and then other side books.

In Physics try to give equal importance to numericals and theory both.

Other than this you should also study other subjects like English and other optional subject on weekends.

If you study well thoroughly then I can assure you that you will surely pass with flying colours and you will really get very good marks.

Hope this helps. 

Best of luck. 

Hey!

For a better and efficient knowledge , a consistent study is needed.  You can also complete your whole syllabus in two months and may be can even get better marks than consistent study , but you will forget everything after some days of study. Then that type of study is not efficient at all . And i think it is of any use else than getting marks.

So i suggest you to maintain a proper time table and give your studies some hours of your day daily..

Hope it helps!

Hey,

it purely depends on person to person. If you like studying one subject very deeply and do not get bored in that manner you should implement this idea. But I believe that changing subjects frequently is more effective as is becomes less boring for a person. But then it also depends on the person. So try studying one subject for a week if you feel that’s better for you, you can go for it.
