Hello Neeraj Kumar,

I had got a 87% in my science boards and cleared my BITSAT exam in the first atempt too.

First I will give you some pointers regarding how study about the boards-

• Hardwork is the key and dont keep in mind that this subject is good or this subject isn't as to get a good percentage you wil require to excell in all the subjects. Have you always been strong in certain topics? Do you tell yourself that your success is a result of your inborn intelligence and natural skill? Conversely, have you told yourself you’re just “bad” at something and no matter what you do, it will always be hard for you? Well, this line of thought is hurting your ability to learn and improve your performance. Studies show that people who think that ability is innate tend not to work hard or persevere. In fact, a growth mindset (the belief that intelligence is not fixed and can be developed) is a comparably strong predictor of achievement.
• Believing that multitasking is easy, especially during class or studying. Focusing on two or more tasks at a time is a fact of life, but believing that you can do more than one thing at a time effectively is a myth. You may convince yourself you have both read up on the contraindications for a new medication and listened to your mom berate you for not calling often enough at the same time, but neuroscience studies show that your brain was in fact switching back and forth between these two tasks, and you are likely to have missed important information in the meantime. Nancy K. Napier, PhD, in Psychology Today says, “That start/stop/start process is rough on us: rather than saving time, it costs time (even very small micro seconds), it’s less efficient, we make more mistakes, and over time it can be energy sapping.”
• Dont waste a lot of time consolling yourself and start working on your goal of acieving them.
  
• Use the technology for your boon rather than using it as your bane.

Now for your BITSAT-

You need to keep all the above points in your head and study simultaneously for both the exams. Once you have your basics correct while you study for the boards then BITSAT will be a piece of cake for you.

I would also reccomend you to join separate coaching or tuitions so that they can help you prepare for the types of questions the exam has up for you.

Here are some of the books i would suggest you to read which I read personally-

For physics- HC Verma, DC Pandey

For Chemistry- I used to do my NCERT thrughly

For Mathematics- I used to practice the questions given to my in the coaching and then the NCERT to clear my basics.

Once youu have your basics clear you would easily clar both the exams with flying colours.

Comment if you have any other queries

All the best!!

If you want to focus on both BITSAT and Board exam then, you should first focus on boards as you will cover most of the syllabus by preparing for boards and also you will be able to clear your basic concepts which is very important for clearing any entrance examination.

For additional preparation of BITSAT, you must focus on your speed of solving problem, as problems in BITSAT paper are quite easy but are too many to solve in the given time. So focus on your speed as well as your reasoning skills. Also, you should focus on your English proficiency especially written, as English too can increase your score in this paper. All you have to do is clear your concepts and daily solve a previous year paper of BITSAT for checking your speed of solving because giving regular tests will prepare you mentally and physically for the exam.

Hope you have got your answer.
