Candidates preparing for JEE Main chemistry can check here chapter-wise syllabus with weightage. Every year NTA releases the official PDF for JEE Main Chemistry syllabus for the exam of both Paper 1 and Paper 2 in September 2019. JEE Main Chemistry notes comprise of three different parts which are Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. The complete Chemistry syllabus carries a total weightage of 33.3% i.e (360 Marks) which can be answered within 50 minutes.
JEE Main Chemistry is just around the corner. It is now that students require to shift gear if they want to pass one of the most coveted engineering entrance exams. It is time to move to a smarter preparation that will work for you. JEE Chemistry is one of those subjects that are scoring and it appears to be a key one for JEE Main 2019. Since the JEE Main syllabus is vast and your preparation covers the board exams too, it is right that you study at the priorities facing you. SelfStudys brings you the JEE Main Chemistry Notes to help you work towards progress in your goal.
If a student dreams to pursue engineering from one of the best NITs or IIITs or even the good GFTIS, understanding JEE Main preparation tips that allow cracking the exam becomes mandatory. NTA will conduct JEE Main twice a year. The first session will be conducted from January 6 to 11 whereas, and the second session will be held from April 3 to 9, 2020. The Paper I will be fully computer-based, whereas Paper-II will be held part computer-based and part pen-and-paper based. JEE Main Chemistry notes will aid the students to draw a clear plan so that they have a good possibility of cracking the exam. Some tricks of the trade, if followed can help the students sail through the exam with ease. Some of the valuable JEE Main Chemistry notes include management of time during preparation and the exam, the important chapters, and topics to focus on as per weightage gave, practising with the previous year question paper, sample papers and taking mock tests on a regular base to name few. Knowing the chapter-wise analysis from the past year papers is another useful tool while preparing for JEE Main Chemistry.
A study of previous years papers, expert tips, topper experiences- these are invaluable to know how to study and get good marks in Chemistry. The preparation can be made goal-oriented if you know what chapters are more important, which ones have usually been covered more in the past examinations, how to remember the formulas and such. The JEE Main Chemistry notes for spells the preparation strategy with specific emphasis on the chapters, weightage and books. Let us tell you that the basic concepts and chapters must be completely covered. There is no reason to leave out any chapters for the exam. The JEE Main Chemistry and Class 12 exam preparation can be clubbed for this goal. Best book solutions to do this are the ones from NCERT. Read them to strengthen your grip on the subject and move on to the additional books delving deeper into the chapters.
One of the major aspects of JEE Main Chemistry Preparation Tips is that you must make short notes as you go through each of the chapters. This is a good reference tactic during the last days of the examination as it allows you to check the chapters without opening the textbook and going in detail.
Make Flashcards for the formulas and chapters you feel you need to be clear with. Just a look during the last days will sort them out for you.
Manage Time Well: One of the most important Chemistry preparation tips is time management. Students should make a timetable and must ensure that they adhere to it. Within specified time they should finish the syllabus. For these students must make certain goals. Depending on the difficulty level of the chapter, a student must decide for themselves in how many times they will be able to finish it. Before moving towards the new chapters, students must ensure that they finish the previous one. Revise completely as it will prove fruitful for the students a month or fortnight before the examination.
Be Thorough with the Syllabus: Students must be well versed in the syllabus of JEE Main Chemistry. They should know the chapters from which the questions will be asked. This will support them to divide their time. Hence JEE Main Chemistry preparation tips include being extremely thorough with the syllabus of JEE Main. Along with the syllabus, students are advised to be familiar with the JEE Main examination pattern.
Important Books for JEE Main: While preparing for the engineering exam, students must prepare for the best kind of books. Beating about the bush will not produce the desired result. Students should not use too various reference books. They should commence their preparation by going through the NCERT Books Class 12 and also go through the study material that is given by the coaching centre from where they have studied. This JEE Main Chemistry preparation tips related to studying from the right books hold a lot of significance since students cannot afford to waste their time preparing for unsuitable study material.
Start your JEE Main Chemistry preparation early: JEE Main Chemistry is a tough exam and if you half-prepared there may be possibilities that you may lose it. So, to succeed you want to prepare well. And preparing well, in essence, means preparing advanced. Now must have a question, why start early? As an early starter, you will have time to twitch your preparation if you run off track. For example, if you are staggering in a particular chapter or topic, you will have time to choose if coaching is the way forward, or you require some other type of intervention. With sufficient time to prepare, you will be ready to keep things under control and not panic as examination date approaches, assuming you use your time reading and practising the hard questions.
Refer recommended books: Buy the book and solution that you can follow and reach every chapter of the syllabus in detail. Solution will have lots of examples to aid comprehension of concepts. They will also have fewer mistakes and ambiguous comments. NCERT Chemistry Class 11 and 12 books are an example of good books and are a good material to build preliminary concepts. Also, note not all solutions by foreign writers are good, just like not all Indian authors are bad. JD Lee is a great asset for the physical chemistry section, while Modern Approach to Chemical Calculations by RC Mukherjee is an equally good book for mastering numerical problems. As a note of warning, avoid solutions that use language that is too tough or is too advanced.
NCERT Books: NCERT Chemistry books on their own are not enough to answer all question asked in JEE Main Chemistry, and you have to read other writer books as well for holistic JEE Main preparation. But that being said they are the most solid material for building the fundamentals of all the chapters included in the syllabus. You must particularly pay attention to the highlighted exercises presented in these NCERT books, as they are the key to knowing basic theories of the chemistry and pave the way for you to know concepts you will come across in higher-level chemistry texts such as Atkins. To get more of these books, practising questions from NCERT Chemistry Exemplar is also recommended.
As we know, it is important to understand the JEE Main Chemistry syllabus and important chapters, which will help you in preparation for JEE Main accordingly. Moreover, you can also download the JEE Main Chemistry Notes PDF at the end of the post.
