JEE Advanced

Read from NCERT textbook as its the best book to study Organic Chemistry for JEE. Try to understand mechanisms of the reactions (not all, only important ones). This helps in memorizing similar types of reactions in one go. Don't cram all the reactions and concepts. Look up past year JEE papers and observe the trends. There must be some reactions in your books that are never taught/asked. They can be left and ignored. Draw flowchart of reactions on sheets of papers. Those sheets should be looked upon regularly so that the chart gets memorized easily. Keep thinking of reactions and mechanisms in your free time. Remove any kind of fear for Organic Chemistry from your mind. Useless fear hampers your ability to understand and enjoy the topics.

The cut-off marks for JEE Advanced varies from year to year and also depends on the category you belong to. As per the latest information available, the qualifying cut-off for JEE Mains 2022 for general category students was 89.7548849 percentile, which corresponds to a score of 105 marks out of 300. As you have mentioned that you have scored 72 marks in JEE Mains 2nd attempt in 2022, it is unlikely that you will be eligible to appear for JEE Advanced 2022 as you did not meet the qualifying cut-off for the general category. However, please note that the cut-off marks for JEE Mains and JEE Advanced may change based on various factors, including the difficulty level of the exam and the number of applicants, so it is best to check the official website of JEE for the latest information on the cut-off marks. It is also important to note that JEE Advanced is only open to the top 2.5 Lacs candidates who qualify in JEE Mains, so even if you had MET the cut-off, there is still no guarantee that you would have been eligible to appear for JEE Advanced.

Hello Fathima from your question its realise that you are asking from starting phase like fresher how to prepare for mains and Advance so , From starting Firstly devote to 10-12 hours daily to yours Study.
start from Basic Mathematics like Differentiation , Integration , Logarithm Function, Modulus Function, Greatest Integer Function .
After the Completion of Basic Mathematics then Start Physics , Mathematics, Chemistry.
One of the most important things that is required in this examination is that patience so keep patience and study with consistency Like in Mathematics:
After Basic Mathematics start from
Sets
Trignometry
Permutation and combination
Sequence and Series
Quardic Equation
Complex number
Binomial Theorem
similarly in this way gradually your maths syllabus will complete .
and at the same time similarly complete physics and Chemistry syllabus in this way at last you feel that your preparation will be complete.
in the last i want to conclude my answer
Firstly Start any topic from Basic and focus on concept By Using This Steps you can prepare for JEE Mains and Advance.
1. Attain All lecture.
2. Make proper Notes.
3. Proper Revise of Notes.
4. Solve Topic wise question
5. Do maximum question as much as you can.
6. And in last Attempt Mock Test
