It usually starts at dinner: “All my tests are online now. I need a new phone.” Half of that is true. The tests are online. But the exam your child is preparing for is not taken on a phone, and that should shape what you buy and the rules that come with it.
Does a JEE aspirant need a laptop or a phone for online tests?
JEE Main is a computer-based test, sat on a computer at an exam centre, not on a personal device. Public broadcaster All India Radio News reported on 3 April 2026 that NTA was conducting the April session in computer-based test mode for around 11 lakh 23 thousand candidates, at around 566 centres in 304 Indian cities and 14 cities abroad.
NTA's official mock test page says its mock tests are there “to familiarize the students about processes of Computer Based Test (CBT)”. You pick JEE Main from a menu and start the test in a browser.
So the honest answer is: for full-length mocks, a laptop or desktop. A phone helps with short practice, but it is the wrong tool for rehearsing a full paper at a desk.
Why practise mock tests on a computer screen and not a phone?
Reading on a screen is not the same as reading on paper, especially under time pressure. A 2018 meta-analysis in Educational Research Review by Delgado, Vargas, Ackerman and Salmerón pooled 54 studies from 2000 to 2017 with 171,055 participants. Readers understood texts better on paper than on screens, the paper advantage held for informational texts but not for purely narrative ones, and it grew when reading was timed.
Your child cannot choose paper for JEE Main. What they can do is get used to timed reading on the kind of screen they will face, so the switch on exam day feels familiar. A phone adds problems a computer does not: a small view that hides diagrams and long options, notifications sliding in mid-question, and a habit of answering while lying down.
Practise the rough work too. In the exam, working happens on a sheet beside the screen, not on the question. Our guide on how to organise rough work in a computer-based exam shows a layout worth copying in every mock.
What device does your child actually need?
Ask these questions before anyone visits a shop:
Is there a working computer at home that runs a modern browser? If yes, full mocks can start this week, at no cost.
Does the coaching test series name system requirements? Ask for them in writing, and check whether it needs a webcam or a particular browser.
Will the device sit on a desk in a shared room? A laptop on the dining table is easier to supervise than a phone in a bedroom.
Is the current phone simply slow, or broken? A phone that runs a test app and a calculator is enough for short practice. NTA's Abhyas app page links to the app on both Android and iOS.
A worked example: a family has set aside money for a phone upgrade. Their son already has a working, three-year-old phone, and there is no computer at home. Spending that money on a basic laptop, rather than a newer phone, gets him the exam-like screen for full mocks, while his old phone carries on handling quizzes. If the budget cannot stretch, a relative's laptop on mock days or a school computer lab are worth asking about before buying anything.
What phone and laptop rules work for a JEE aspirant?
UNESCO's 2023 Global Education Monitoring Report said that smartphones in schools have proven to be a distraction to learning. The same logic is worth applying at home, so agree on rules before the device arrives, not after the first argument.
Full mocks happen at the desk, at the time of day the real paper runs, with the phone in another room.
The laptop stays in a shared space and is used for tests, review and study material.
Phone study time runs in Focus mode, which you can set up together using our guide to setting up Focus mode on a teen's phone.
Every mock is followed by a review session the next day, not just a score check.
For mock day itself, our guide to simulating real exam conditions at home covers timing, breaks and the room.
When a mistake comes from using the wrong method, the Fermi Problem Library has worked problems with a step-by-step solver that explains the reasoning rather than printing an answer, which suits a laptop session after a mock.
What should you say when they ask for a new phone?
Try something like: “You're right that tests are online. The real exam is on a computer, so let's get you practising on one. Your phone stays for quick revision. Let's write down the rules together, and we'll look at them again after your next three mocks.”
Start with the next full mock: on a computer, at a desk, phone outside the room.
