Top Entrance Exams for 12th Science Students in India

Introduction

Just passed Class 10 and love science? Whether you're into building cool things, curing diseases, or unlocking the universe’s secrets — and have a PCM, PCB, or PCMB background — here’s a quick look at exams that can shape your future.

Science Entrance Exams After Class 12

Let's be honest: the competition is tough. But if you’ve got the passion and you’re willing to prepare, you’re already halfway there. Here’s a look at the major entrance exams that open doors to India’s top science institutes:

JEE Mains

Your entryway to prestigious engineering schools like NITs and IISc is JEE Mains. With 75 questions in Physics, Chemistry, and Math, it’s tough—but doable. Clear it, and you’re on track for JEE Advanced and even bigger opportunities.

JEE Advanced

JEE Advanced comes after clearing JEE Mains and is for the top qualifiers only. Conducted by a different IIT each year, it’s taken by around 2 lakh students aiming for IITs, IIST, and IISc. Concepts, quickness, and inventiveness are all put to the test in two demanding 3-hour papers.

IISER Aptitude Test (IAT)

If you're passionate about research and pure science but don’t want to go the JEE/NEET route, IISERs might be your perfect fit. Through the IAT, you can get into IISERs—and even IISc or IIT Madras for select programs. The exam covers all four subjects: Physics, Chemistry, Biology, and Math. About 40,000 students appear each year, so it’s a bit less competitive. Scored 60% in Class 12 (or 50% if you're SC/ST/PWD)? You’re eligible to apply.

NEET

NEET is the key to top medical colleges like AIIMS and science programs at IISc and BHU. With 20+ lakh candidates, it’s tough. A 720-mark paper tests PCB skills. If you possess 50% of the Class 12 PCB/PCMB, you are eligible.

BITSAT

The BITSAT is a brief test that is administered by BITS Pilani and its campuses in Hyderabad and Goa. This three-hour online test assesses your command of PCM, English, and logical reasoning. Candidates must have completed Class 12 within the last two years and have an overall PCM score of 70%.

NEST

Want to join NISER or CEBS? Crack NEST — a science-focused exam for sharp minds. It’s 3 hours long, with flexibility to choose Math or Biology, perfect for PCM or PCB students. You must’ve passed Class 12 in 2023, 2024, or 2025.

CUET

Introduced in 2021, CUET is your gateway to Central and many private universities. It tests domain subjects, reasoning, and language skills. With 9+ lakh takers, it's growing fast—and yes, one form covers multiple colleges. Simpler, smarter admissions!

ISI Entrance Test

If you're up for the task, ISI (Indian Statistical Institute) provides excellent degrees in data science, statistics, and mathematics. The exam lasts four hours and consists of two sections: UGA (MCQ) and UGB (subjective).

CMI Entrance Test

Chennai Mathematical Institute (CMI) may be small, but it's a powerhouse in math, physics, and computer science. Its 3-hour pen-and-paper test has a 40-mark objective and 60-mark subjective section. Eligibility? Just clear Class 12—no frills, just talent.
