The IAT 2026 exam is scheduled to be held on June 7, 2026, while the NEST 2026 exam will be conducted in online/ CBT mode on June 6, 2026, at multiple exam centres across the country. Since there is no gap between the two exams, aspirants require a smart combination of conceptual clarity, consistent practice, and exam-level exposure.
Over the past few years, SciAstra has emerged as one of the most focused platforms exclusively dedicated to research-oriented exams like IISER, NISER, IISc, and related institutes. Unlike traditional coaching platforms that primarily target JEE or NEET, SciAstra designs its courses, books, and mock tests specifically for IAT and NEST aspirants. This makes it a one-stop solution for students aiming to build a career in pure sciences through exams like the IISER Aptitude Test (IAT), NEST, CMI Entrance Test, ISI Admission Test, and IACS exams.
Based on an analysis of the NEST and IISER 2026 syllabus, a substantial portion of the content overlaps. Test takers can save time by identifying common topics and preparing them first with strong conceptual clarity. Well-structured IAT/NEST courses and IAT/NEST books for preparation should include syllabus mapping, focused study sessions, regular practice questions, mock tests, and continuous revision.
In this detailed blog, we will explore the best SciAstra courses, books, and mock tests for IAT and NEST 2026, along with strategies to use them effectively for maximum results.
