The main thing is that you have to build your concentration level, then only you can stay focused on your goal. I would like to say that please limit the study time between 10 to 12 hours and please increase your concentration and speed of reading, understanding and solving the problems then you will not face any kind of difficulty.For preparation of exam, the most important thing is your confidence after that you should know the whole syllabus and make your plan properly for learning new chapters, solving the numericals and revision. All three things should be the part of your preparation strategy in daily routine.

You don't need to worry that much about it as with two subjects out of three you can qualify any entrance exam with good marks you just need to believe in yourself .Don't loose your confidence . Just focus on your  study try to solve as many questions as you can .As you said you are good in chemistry try to make it more stronger and also solve problems in mathematics and for physics try to solve basic problem and also focus on modern physics
