  • IISER Kolkata

  • IISER Mohali

  • IISER Bhopal

  • IISER Thiruvananthapuram

  • IISER Tirupati

  • IISER Berhampur

These institutes offer BS-MS dual degree programs, BS programs, Integrated PhD programs, and PhD programs in core science disciplines.

IISER Courses Offered

The primary program offered through the IISER IISER admission process is the 5-year BS-MS Dual Degree Program. Students can specialize in:

  • Physics

  • Chemistry

  • Mathematics

  • Biology

  • Earth & Environmental Sciences

  • Data Science (in select campuses)

Some IISERs also offer:

  • 4-year BS programs

The curriculum is research-oriented, encouraging students to participate in laboratory work and research projects from the early years.

IISER Admission Channels

Admission to IISER IISER programs is conducted through multiple channels. These include:

1. IISER Aptitude Test (IAT)

The primary mode of admission is the IISER Aptitude Test (IAT). It is a computer-based test conducted annually. Most students gain admission through this exam.

3. KVPY Channel (Earlier)

Previously, students could apply through the Kishore Vaigyanik Protsahan Yojana (KVPY) channel. However, this scheme has been discontinued in recent years.

IISER Aptitude Test (IAT) – Exam Pattern

Understanding the exam structure is crucial for IISER IISER preparation.

Exam Mode:

Computer-Based Test (CBT)

Subjects Covered:

  • Physics

  • Chemistry

  • Mathematics

  • Biology

Question Type:

  • Multiple Choice Questions (MCQs)

Duration:

  • 3 hours

Each subject typically carries equal weightage. The questions are designed to test conceptual clarity, analytical thinking, and application skills rather than rote memorization.

IISER Entrance Preparation Strategy

Preparing for IISER IISER requires a strong conceptual foundation and consistent practice. Below are effective strategies to help you succeed.

1. Understand the Syllabus Thoroughly

The IAT syllabus is broadly based on the NCERT syllabus for Classes 11 and 12. Focus on:

  • Core concepts

  • Application-based problems

  • Interdisciplinary topics

2. Master NCERT Textbooks

NCERT books form the backbone of IISER preparation. Ensure you:

  • Read each chapter carefully

  • Solve all in-text and exercise questions

  • Revise diagrams and examples

3. Practice Previous Year Papers

Solving past papers helps you:

  • Understand question trends

  • Improve time management

  • Identify weak areas

Aim to simulate real exam conditions while practicing.

4. Focus on Conceptual Clarity

Unlike some competitive exams that emphasize speed, IISER IISER focuses on:

  • Analytical ability

  • Conceptual understanding

  • Logical reasoning

Avoid rote learning and prioritize understanding the “why” behind each concept.

5. Create a Balanced Study Plan

Divide your preparation time equally among:

  • Physics

  • Chemistry

  • Mathematics

  • Biology

If you are stronger in PCM or PCB, ensure you also strengthen the fourth subject, as IISER tests all four.

6. Take Mock Tests Regularly

Mock tests are essential for:

  • Improving speed and accuracy

  • Reducing exam anxiety

  • Refining strategy

Analyze every mock test to learn from mistakes.

Time Management Tips for IISER Preparation

Effective time management plays a crucial role in IISER IISER success.
