Engineering Entrance Exam

For physics, reference books are: Dinesh+ Concept of physics (Part 1 and 2).
For chemistry, reference books are: O. P. Tandon+NCERT
For maths, reference books are: Dinesh+NCERT
Moreover, go through the last 25 years JEE Advanced question papers.

You are advised to wait for one year and prepare well further.

If you have not done good this year but you think that you perform better and if this is your confidence level then yes, you can drop a year to prepare for JEE Mains. But also remember if you are dropping a year then you have to study really very hard so that you can get a seat in IITs/NITs. This should be your aim.

JEE Mains is held all over India. It is a joint entrance exam which is conducted all over India by CBSE.
Through this exam, you can take admission in the good engineering colleges like NITs/IIITs/GFTIs.

You are advised to take exams conducted at the state level. You are not eligible to take admission in IIT.

Good evening,
It would be better to prepare for GATE while pursuing B.Tech.
It will be helpful for the current course as well as for clearing the concerned exam.
Thanks and all the best.

That will always depend on you and your preparations. If you study well then you can crack JEE Advanced exam.

Hello Maneesh,
No, you cannot. There are 3 attempts for JEE Mains and 2 for JEE Advanced.
So, if you appeared for the same in 2016, then you can appear for JEE Mains in 2017 and 2018 only and for Advanced, you can appear in 2017 only.
Consecutive means the next two years.
So, right now you are not eligible to appear for JEE Mains 2019.

As per me, Cengage is a better textbook.
