JEE Main: How To Prepare At Home, Without Spending A Paisa

JEE Main: How To Prepare At Home, Without Spending A Paisa

Edited By Ramraj Saini | Updated on Apr 19, 2024 07:22 PM IST | #JEE Main

Is it possible to write the Joint Entrance Examination (JEE) Main and clear it without spending anything on coaching?

The JEE Main is the main national-level exam for admission to Engineering and also one of the toughest. Over 14.78 lakh candidates wrote it last in 2024. Because it serves as the preliminary screening test for the JEE Advanced through which students are admitted in the premier Indian Institutes of Technology (IIT), competition is intense.

A large section of candidates writing the JEE Main prepare for years and this has spawned an entire industry of coaching centres and institutes that charge to get them ready for the exam. Students often go to great lengths for coaching – many shift to hubs like Kota in Rajasthan. The best-known coaching classes can charge as much as Rs 1 lakh to Rs 1.5 lakh per year.

However, this is not the only way to crack the JEE Main. It is entirely possible to use free resources online and prepare independently with some careful planning and diligence. Here’s how.

JEE Main Prep: The Phases

When students begin their JEE preparation, then they must pass through a series of phases to do well in the examinations. They will go through these phases:

Phases of JEE Main Prep: Plan, Do, Act and CheckPhases of JEE Main Prep

Plan: Target, Time-Table, Study Material

Planning includes the following steps:

  • Set your target
  • Prepare your time-table
  • Assemble proper study material

The JEE Main is not the kind of examination for which you can wait till the last moment to open your books and still end up scoring good marks. So, one should organise the best routine to complete the syllabus on time. The time-table or routine may vary from person to person but every candidate should have one. You can seek the help of some institutes – they can help the student understand the syllabus and the effort that will be required to complete the exam. Careers360, too, assists with time-table creation. To access that, go to Time-table/Careers360, register free-of-cost. You’ll find the time-table according to the exam you selected during registration.

Do: Tackle The JEE Main Syllabus

This is the “study” part. Once you have a time-table in place, start following it and stick to it. Start by checking the best lectures available – check for quality and understandability, make sure the language is comfortable before starting the full module. Refer to standard, error-free books for reference. Making notes is absolutely vital. The JEE Main syllabus is vast and it is not possible to revise it fully every time. This is why notes that you make yourself are crucial – they allow for speedy revision. After completing any chapter, practice questions from sources available. Make sure that the resources are error-free and have a wide variety of questions. This will both expand your ability to think laterally, tackle a wide variety of questions and build your confidence.

Questions related to JEE Main

Have a question related to JEE Main ?

Hello aspirant,

Unfortunately it is impossible for you to get any good college ( whether government or private) with 64 percentile in jee mains. It is one of the toughest exam of India and its cutoff is also very high. I suggest you to take a drop and give your best for next attempt.

Thank you

Hope this information helps you.


Yes, you can repeat your 12th grade even after passing, including on the Telangana State Board of Intermediate Education (TSBIE). There are several reasons why students choose to repeat a year, such as aiming for higher marks, switching to a different stream, or improving their subject knowledge for competitive exams.

Hope this helps,

Thank you

Yes, you can write the NIOS exam a year after passing 12th standard. There is no restriction on appearing for NIOS based on the gap since your previous 12th board exams.  NIOS qualification is perfectly acceptable for JEE Mains. You just need to meet the eligibility criteria, which includes passing 10+2 with Physics, Chemistry, and Mathematics. JEE Mains considers the year of your first attempt at 12th board exams (NIOS or any other board) to determine eligibility. You can only appear for JEE Mains for three consecutive years after that first attempt year.

Similar to JEE Mains, BITSAT also accepts NIOS qualifications. BITSAT eligibility is based on the year you passed or appeared for your 12th board exams (current year and previous year). So, you can appear for BITSAT the year you take the NIOS exam and the following year as well.

I hope it helps!


With a 69 percentile in JEE Main, it is highly unlikely for your son to secure admission in IIT Bombay. Admission to IITs, including IIT Bombay, is based on the JEE Advanced exam, for which qualification through JEE Main is required. Generally, to qualify for JEE Advanced, candidates need to be in the top 2,50,000 ranks in JEE Main, which typically requires a higher percentile than 69.

Hope this helps,

Thank you


If you have taken a CBSE improvement exam and there is no explicit option to indicate this on the JEE Advanced application form, you should proceed by entering the details of your original CBSE board exam, including the year of passing and marks obtained. Alongside the application, you may need to submit supporting documents, such as a copy of your admit card or mark sheet indicating your appearance for the improvement exam. In case of any uncertainty or if you require further clarification, it's advisable to contact the JEE Advanced exam authorities directly

Hope this helps,

Thank you
