What are the cutoffs for Indian Institute of Science Bangalore in 2026?

For 2026, the headline cutoff at Indian Institute of Science (IISc) Bangalore is the JoSAA Round 1 closing rank of 3552 (JEE Advanced All India Rank, General category) for the newly launched B.Tech in Aerospace Engineering, released on June 13, 2026. IISc Bangalore admits undergraduates entirely through national entrance exams: JEE Advanced and JEE Main (for the four-year B.Tech and the B.S. Research programmes) and IIT JAM (for the Integrated PhD route). Unlike older IISc admissions that ran through a standalone form, the B.Tech programmes now go through JoSAA counselling alongside the IITs. As a reference point from the previous cycle, the most competitive B.Tech branch, Mathematics and Computing, closed at JEE Advanced rank 856 (General) in 2025, so aspirants should benchmark against a sub-1000 General rank for the established programme and the wider 3552 band for the first-year Aerospace seat.

The sections below break the closing ranks down by year, by programme and by category using IISc Bangalore's own published cutoff data so you can judge your admission chances precisely.

Year-Wise Cutoff Trends (2024-2026)

This table tracks how the closing rank for IISc Bangalore's flagship B.Tech in Mathematics and Computing (General category, JEE Advanced) has moved across cycles, alongside the 2026 JoSAA Round 1 cutoff for the new Aerospace Engineering branch. It answers the core question every aspirant asks: is the rank I need going up or down each year? Read the rank as a closing All India Rank in JEE Advanced, where a lower number means tougher competition.

The takeaway: the General closing rank for Mathematics and Computing tightened from 757 in 2023 to 708 in 2024, then loosened to 856 in 2025 as the seat pool and applicant preferences shifted. The 2026 figure of 3552 belongs to the brand-new Aerospace Engineering programme and is not directly comparable to the older branch, because a first-year programme has no demand history; expect it to settle in future cycles once awareness builds.

Course-Wise Cutoff at Indian Institute of Science Bangalore

IISc Bangalore's undergraduate admissions split across two main tracks: the four-year B.Tech and the four-year B.S. (Research) programme, each with its own closing ranks. The table below gives the 2025 JEE Advanced category-wise closing ranks for the B.Tech (Mathematics and Computing) seat and the B.S. (Research) seat, plus the 2026 JoSAA Round 1 General cutoff for B.Tech Aerospace Engineering. It answers which programme is reachable at your rank and how much the bar drops across reserved categories.

The clear pattern: the B.S. (Research) programme is more accessible by rank than B.Tech Mathematics and Computing, with a 2025 General closing rank of 2263 versus 856 for the B.Tech branch. Reserved-category ranks are markedly relaxed, with SC closing at 770 and ST at 616 for B.S. (Research), and SC 265 and ST 257 for the B.Tech seat. The PwD route closes very low at 37-40, reflecting limited supernumerary seats.

B.S. (Research) cutoffs by entrance exam (2025)

IISc Bangalore fills B.S. (Research) seats through three exams: JEE Advanced, JEE Main and IIT JAM (for the Integrated PhD pathway). The table below shows the 2025 closing ranks for the JEE Main route and the IIT JAM route, which matter because a candidate who misses the JEE Advanced cut can still enter through JEE Main. Read each as a 2025 closing rank within that exam's ranking system.

Through the JEE Main route, the 2025 General closing rank for B.S. (Research) was 903, comparable to the B.Tech bar, while SC and ST candidates closed at 581 and 314 respectively. The IIT JAM Integrated PhD General closing rank of 746 in 2025 confirms that the research-PhD entry is sharply selective even though it sits outside the JEE system.

Cutoff Trend Analysis

The B.Tech cutoff at IISc Bangalore has stayed in a tight, elite band rather than rising or falling sharply: the Mathematics and Computing General closing rank went 757 (2023) to 708 (2024) to 856 (2025), a swing driven by how top-1000 JEE Advanced rankers traded off an IISc seat against established IIT branches, not by any dilution in standards. The bigger 2026 story is structural: IISc entered JoSAA counselling and launched three new B.Tech branches (Aerospace Engineering, Mechanics and Computing, Materials Science and Engineering) alongside Mathematics and Computing, and the first-ever Aerospace Engineering General cutoff landed at JEE Advanced rank 3552 in JoSAA Round 1. Because this is a debut programme with no historical comparison, that 3552 figure is likely to tighten in later rounds and future years as candidate awareness grows. Realistically, a General-category aspirant should target a JEE Advanced rank inside the top 900 to be competitive for Mathematics and Computing, while the new branches and the B.S. (Research) programme (General closing 2263 in 2025) offer genuine room up to and beyond rank 3000. Reserved-category candidates have meaningfully wider windows, with SC and ST B.Tech ranks closing around 265 and 257 in 2025.
