Yes it's worth because the exam is similar to 11th and 12 th sallybus with the flow you're going to understand and be smart in those subjects

Hello student ,

No, it is not worth and the main reason is shortage of time. Pressure is the main reason behind the sudden rise in hard work which may or may not be worth it. Few try their best from the day one of class 11th .Even the teachers start pressurizing students. But, the aspirant might take it in other way and work hard until he reaches his extreme point . If you are familiar with JEE exam concepts a little bit at the beginning of class 11 then, it will be easy for him to work hard.But, what about those who were not familiar with the whole JEE concept, they struggle to work hard.

They might be forced to join the JEE course. After the beginning of grade 12, the aspirant has to concentrate both on boards and JEE. He cannot neglect either one of them. JEE is based on NCERT but, it requires a lot of hard work. There are a lot of models of questions that might be important for JEE but not for boards. So, after the beginning of grade 12 there is a war between boards and JEE. Some can make peace between both the parties. But, some cannot, in that case, if either one lose then it is a huge loss for the student. Some even spend one year to prepare for JEE. Is it worth to work hard for a year or get less in boards? No obviously not ..

Hope it will help you !
