Hi

There are many entrance examination for engineering or BTech but preparation for which entrance examination are you asking about?

I am guessing that you are asking about JEE Mains examination .

First of all remove the thought from your mind that your PCM is below average , there is nothing like that it all depends upon the amount of effort you put in towards your studies and if you prepare with dedication and study with concentration then you can definitely do well in your entrance examination.

Follow the below tips:-

Go through your syllabus and as you have less time, focus and stress more on  important and scoring topics or chapters which are listed below subject wise along with their chapter wise weight age based on past year papers :-

PHYSICS

*Modern Physics:- 20 marks
*Heat and Thermodynamics :- 12 marks
*Optics:- 12 marks
*Current Electricity :- 12 marks
*Electrostatics :- 12 marks

*Make routine or timetable :- you can make a routine as well and try to give at least 8 hours or more to study , your routine should revolve around things i.e study, revise and practice

• PHYSICS is the  toughest part for most of the aspirants  as it has both numericals and concepts to deal with , so keep at least 3 hours each day for Physics.
• In Chemistry you have to deal with reactions and learn them and solve questions as well, so give at least 2 hours daily to Chemistry
• Mathematics is all about practising questions, so try to give at least around 3 hours each day for maths

*After completing each chapter , you should go through mcqs and numericals of the same chapter

*Make short notes of important formulas and concepts for each chapter and Keep revising it

*Solve previous year JEE MAINS questions , it will let you know the examination pattern, type question etc so that you can prepare accordingly

*Go through JEE MAINS mock test papers , it will let you know your preparation level and and weak areas so that you can work on them and perform well in your examination
