FAQs
How much time is required to prepare for the JEE Mains exam?
Although maximum candidates usually require one or two years to prepare for the JEE Main and the JEE Advanced exam, candidates can also ace these exams with a tight study routine of 6 months.
Is HC Verma enough for the JEE Mains physics preparation?
HC Verma is considered to be a good book for the JEE Main preparation. It comprises good explanations and many practice problems. However, it is not enough for the preparations and candidates are required to study the NCERT textbooks as well.
Is the JEE Mains physics paper easy?
The physics section in the JEE Main exam is typically of moderate level of difficulty. It comprises a mix of numerical and concept-based questions.
Is 75 marks compulsory in the JEE Mains exam?
Candidates must keep in mind that there is no requirement of 75% marks in class for appearing in the JEE Main exam. The JEE Main eligibility criteria of minimum 75% marks in class 12 is required at the time of admission in NITs, IIITs and GFTIs. Candidates can apply and appear in the JEE Main exam irrespective of their class 12 marks.
What are the questions asked in the JEE Main exam?
The JEE Main exam has a total of 90 questions from all three subjects. The JEE Main exam has 30 questions each from the subjects of Physics, Chemistry and Mathematics. Out of 30 questions, there are 20 multiple choice questions and 10 are questions with numerical value answers.
Is NCERT enough for the JEE Mains preparation?
The official syllabus of JEE Main entrance exam and NCERT books cover almost all topics, and it is preferred by the candidates for their preparation. The syllabus of JEE Main and that of CBSE's Class 11 and 12 board is almost the same. Candidates can consider NCERT books as one of the best reference materials for the JEE Main exam.
Can candidates get admission into NIT with 35,000 rank in the JEE Main exam?
Some NITs and IIITs which candidates can get with 35000 rank in the JEE Main entrance exam are Indian Institute of Information Technology Kalyani, National Institute of Technology Mizoram, Indian Institute of Information Technology Dharwad, National Institute of Technology Nagaland, and National Institute of Technology Manipur.
Is it easy to score 99 in the JEE Mains exam?
The exact marks to be obtained for getting the 99 percentile in the JEE Main exam depends on the difficulty level of the paper. If the JEE Main question paper turns out to be easy, then marks secured by most of the candidates are good and the higher percentile is relative and gets pushed for higher marks.
Is 40 considered to be a good score in the JEE Main exam?
No, 40 is regarded as a very good score in the JEE Main exam. Since 85 to 95 percentile is considered to be good for admission into NITs, and IITs, securing anything less than that is not a good score for the General, OBC, and EWS candidates. With this score, such candidates can barely make it through a few engineering colleges of India.
