Is my child's hard work in 12th science for JEE not paying off? How can I help?

Ans: Hello Jigar.
In general, I would like to say one important thing:- Almost 90% of students are suggested to prepare for JEE / NEET either by relatives, friends, or parents without understanding their capabilities. The success rate in JEE is very very low. Now related to your question, you say, your son is preparing for JEE and is unable to score better in tests conducted by tuition classes. Hard work has less relation to success in the examination. To achieve success, no doubt one has to do hard work but in a smart way. Sitting on a chair for hours is not hard work. Ask your son,
(1) where he is comfortable with all the teachers and their teaching methodology.
(2) Is he comfortable with the syllabus of JEE
(3) Take a review with all the subject teachers about his presence in the class and attention towards listening.
(4) Ask him about the speed of calculations to be done with the problems in PCM
(5) Whether doubt sessions are conducted by classes. And if yes, then where he is taking the benefit of it or not?
(6) Check his reading speed. Along with reading, check his understanding speed also.
(7) Discuss with his school teachers to ask if he was good in Maths and science. (School marks matter less in JEE preparation)
(8) How many hours are the coaching classes conducted? If they are conducted for 4-5 hours, then it is OK. But if more than that, then ask the class administration for reasons.
(9) Apart from existing tuition, join him on other online test platforms.
(10) If he is disturbed, demotivated, and undergone depression, then do not force him to prepare for JEE. It is better to withdraw from it and focus on the state-level CET examination.
