There is no certainity that only with coaching you can score better in JEE. As per a report by JEE Advanced, more candidates qualify JEE with self study than candidates with coaching. There are students who take extensive coaching, but still are not able to crack or qualify the exam, whereas on the other hand, there are study who prepare on their own for JEE and still manage to crack the test. Actually, it depends on so many factors closely associated with cracking the test. Are you basic concepts of Physics, Chemistry and Mathematics fundamentally calear or is it just a theortical study. Theroritical study will not help in JEE. To what extent have you studied from NCERT books, which are considered to be the best sources to study from for JEE. Whether you are able to complete the syllabus and revise what you have studied. These are some questions you must ask yourself and take in consideration for JEE preparation.
