LEET

Focus more on Applied Physics and Applied Mathematics as they cover 50% portion of the syllabus. If possible, buy a decent book for Applied Physics as it should be completely different field for you. Alternatively, you can find online tutorials available on the internet. Practice as many numericals and maths problems as possible for the topic you prepared. As you have bought the book for it, you can try problems from Singh & Singh, but don't rely on it for solutions. Use your own intuition and concepts. If in doubt, you can always use Internet for help. You should also prepare your computer Science part side by side because often we think that we know something very well and ignore it completely, but that part also makes a difference. Don't indulge into the details of the topic too much, you can gain a deeper knowledge about it but it will take your much time and very less time is left in the end for other topics. So, cover all topics. Don't leave any thinking it will not come in the exam. If you are preparing Applied Mathematics first, then cover each topic and then devote much time in practice only. The difficulty of the questions is not very high and generally requires 3-4 steps at max. So, prepare accordingly. Prepare your daily schedule chart and follow it disciplinary. Apart from weekdays, give extra study hours on weekends. Give mock test once a week so that you can evaluate your performance and focus more on the topics that you think you should. Hydrate yourself sufficiently.
