The Indian Institute of Science (IISc), Bengaluru, is participating in JoSAA counselling for the first time in 2026. Until 2025, IISc conducted its own separate admission process for its sole BTech programme in Mathematics and Computing. From AY 2026-27, all four BTech programmes at IISc, including three newly launched ones, will be admitted exclusively through JoSAA 2026 based on JEE Advanced 2026 All India Rank. Candidates no longer need to apply separately on the IISc admission portal for BTech; registration on josaa.nic.in is the only step required.
Critical distinction: The IISc BS (Research) programme is entirely separate from the BTech and is NOT part of JoSAA. The BS Research programme runs its own admission process at bs-ug.iisc.ac.in, accepting JEE Advanced and IISER IAT scores, with a 2025 JEE Advanced closing rank of AIR 2,263 for the Open category. This guide covers only the BTech programmes admitted through JoSAA 2026.
IISc Bangalore Joins JoSAA 2026
IISc Bengaluru's entry into JoSAA 2026 represents a significant structural change to the national engineering admissions ecosystem. Previously, top JEE Advanced rankers interested in IISc had to navigate two separate admission processes simultaneously. From 2026, IISc BTech seats are part of the same JoSAA choice-filling interface that candidates use for IIT choices, making it straightforward to compare and rank IISc options alongside IIT programmes during counselling.
IISc is ranked first in India by NIRF 2025 in the Research category and features among the top 100 globally in the Times Higher Education Interdisciplinary Science Rankings 2026. Located in Bengaluru, India's technology and startup hub, it offers a deeply research-integrated undergraduate environment. The table below presents the key parameters of IISc BTech admission through JoSAA 2026.

IISc Bangalore Admission Process Through JoSAA
The admission process for IISc BTech through JoSAA 2026 follows the exact same sequence as IIT admissions: JEE Advanced qualification, JoSAA registration, choice filling, mock allotment, round-wise seat allotment, and online reporting. Candidates do not need a separate application, separate login, or separate fee payment to IISc before allotment. IISc seats are treated on par with IIT seats within the JoSAA framework; the SAF structure, reporting deadlines, and Freeze/Float/Slide options all apply identically.
Step | Action | Details |
|---|---|---|
1 | Qualify JEE Advanced 2026 | Only JEE Advanced qualifiers are eligible; JEE Main rank alone does not grant access to IISc BTech |
2 | Register on josaa.nic.in | Use JEE Advanced 2026 registration number and password; JoSAA registration and choice filling opened June 2, 2026 |
3 | Fill choices during choice filling | Select IISc BTech programmes (Aerospace Engineering, Materials Science and Engineering, Mathematics and Computing, Mechanics and Computing) as preferred choices; rank them in order of preference |
4 | Participate in mock allotment | Review mock allotment result to assess likely seat allotment before final locking |
5 | Lock choices | Finalise and lock the choice list before the deadline; locked choices are binding for allotment |
6 | Check Round 1 seat allotment | If allotted an IISc seat, download the provisional allotment letter from josaa.nic.in |
7 | Complete online reporting | Pay Seat Acceptance Fee (SAF), upload documents, and select Freeze/Float/Slide by the Round 1 reporting deadline (June 26, 2026, 5:00 PM IST). Choice locking closed June 11, 2026; Round 1 allotment released June 13, 2026 |
8 | Physical reporting at IISc | Report to IISc Bengaluru campus for document verification as per the date mentioned in the allotment letter |
Eligibility note: IISc BTech eligibility follows the same Class 12 criteria as IITs: minimum 75% aggregate marks across 5 subjects (Physics, Chemistry, Mathematics, one Language, and one elective) in Class 12 or equivalent (65% for SC/ST/PwD), as prescribed in the JoSAA 2026 Business Rules. The 75% threshold applies to all five subjects in aggregate, not to PCM alone. Candidates who appear for Class 12 in 2026 or passed in 2025 are eligible. No age limit applies.

Expected IISc Bangalore Cutoff 2026 for JEE Advanced Candidates
The only BTech programme with historical JoSAA cutoff data at IISc is Mathematics and Computing, which previously ran its own admission process. In 2025, the Open Gender-Neutral closing rank for Mathematics and Computing was AIR 856, with an opening rank of AIR 37. The three new programmes (Aerospace Engineering, Mechanics and Computing, Materials Science and Engineering) have no historical data, as this is their first year of admission. Expected cutoffs for new programmes are estimates based on IISc's overall competitiveness and the rank bands where candidates are likely to consider interdisciplinary non-CSE choices.
Programme | 2025 Closing Rank (AIR, Open GN) | 2026 Expected Closing Rank (AIR, Open GN) | Notes |
|---|---|---|---|
Mathematics and Computing (existing) | 856 | 800 to 950 (estimated) | 2025 saw closing rank of 856 for Open Gender-Neutral; 2026 expected in similar range pending seat increase if any |
Aerospace Engineering (new) | No 2025 data; first year offering | 1,200 to 2,000 (estimated) | New programme; no historical data; expected to be competitive but more relaxed than Mathematics and Computing in the first cycle |
Mechanics and Computing (new) | No 2025 data; first year offering | 1,200 to 2,000 (estimated) | New programme; interdisciplinary focus; expected demand from robotics and computing aspirants |
Materials Science and Engineering (new) | No 2025 data; first year offering | 1,500 to 2,500 (estimated) | New programme; niche field; expected to attract advanced material science and research-oriented candidates |
Category-wise OR-CR data for Mathematics and Computing in 2025 (the only year with JoSAA-equivalent IISc admission data) and 2026 Round 1 figures after June 13, 2026 are available at josaa.nic.in under the OR-CR section. The table below presents available 2025 category data for Mathematics and Computing as a reference benchmark.
Category | Maths and Computing 2025 OR-CR (AIR) | Notes |
|---|---|---|
Open, Gender-Neutral | 37 to 856 | Consistently the most competitive pool at IISc BTech; top 850 AIR range |
Open, Female-Only | Published on josaa.nic.in | Supernumerary seats; more relaxed than GN pool |
OBC-NCL, Gender-Neutral | Published on josaa.nic.in | OBC category rank; not CRL; check josaa.nic.in for exact OR-CR |
EWS, Gender-Neutral | Published on josaa.nic.in | Introduced in 2019; falls between Open and OBC range typically |
SC, Gender-Neutral | 265 (SC category rank, Round 1 2025) | SC category rank; considerably more relaxed than Open GN in equivalent CRL terms |
ST, Gender-Neutral | Published on josaa.nic.in | ST category rank; most relaxed cutoff across all categories |
PwD | Published on josaa.nic.in | Horizontal reservation over base category; check josaa.nic.in for sub-pool OR-CR |
Important caveat on new programme cutoffs: Cutoff estimates for Aerospace Engineering, Mechanics and Computing, and Materials Science and Engineering are directional only. First-year cutoffs of new programmes at prestigious institutions are difficult to predict accurately because demand depends on candidate preference distribution, awareness, and willingness to choose newer programmes over established IIT options in the same rank band. Candidates should file these programmes as choices if they are in the AIR 1,000 to 3,000 range and are research-oriented.

Who Should Choose IISc Bangalore Over IITs?
IISc BTech is not the right choice for every strong JEE Advanced qualifier. It is a highly specific fit for a particular profile of student, and candidates should evaluate the comparison honestly before locking choices. The table below presents a direct head-to-head comparison across parameters most relevant to an undergraduate candidate's decision.
Parameter | IISc BTech | IIT BTech |
|---|---|---|
Programme Scope | 4 focused programmes only: Aerospace Engineering, Materials Science and Engineering, Mathematics and Computing, Mechanics and Computing | Wide variety: CSE, EE, ME, CE, Chemical, Metallurgy, and 30+ specialisations across 23 IITs |
Research Integration | Exceptionally strong from Year 1; access to globally ranked research labs and faculty across 40+ departments | Varies by IIT; research opportunities strongest at IIT Bombay, Madras, Delhi, Kanpur, Kharagpur |
Campus Environment | Single unified campus; deeply interdisciplinary; smaller UG cohort (125 BTech seats total) | Multiple IITs; large UG batches; campus culture varies significantly by location |
Degree Awarded | BTech from India's top-ranked research institution (NIRF Rank 1 in Research) | BTech from one of 23 IITs; brand value varies by IIT rank |
Post-graduation Pathway | IISc PhD or integrated PhD pathway; strong GATE exemption prospects; high conversion to research careers | IIT MTech; IISc MTech/PhD; international MS/PhD; strong industry placement at top IITs |
Industry Placement | Limited but growing; Bengaluru location provides startup and tech industry access; first BTech cohort yet to graduate | Extensive placement record; top IITs report packages up to Rs. 1 Cr+ in CSE |
Tuition Fee | Rs. 2 lakh per year (Rs. 8 lakh total); actual first-year statutory cost is Rs. 2,20,800 for General/OBC/EWS (includes deposits, gymkhana, student funds); SC/ST/PwD pay Rs. 20,800 total in first year (tuition fully waived; only deposits and statutory charges applicable) | Rs. 1 lakh per semester (Rs. 8 lakh total); SC/ST/PwD get full tuition waiver; non-tuition charges additional |
Location | Bengaluru; India's technology and startup hub; access to leading tech companies and research institutions | Varies; Mumbai, Delhi, Chennai, Kanpur, Kharagpur etc. |
Cutoff Competitiveness (Open GN) | Mathematics and Computing closes at AIR 856 (2025); new programmes expected AIR 1,200 to 2,500 | IIT Bombay CSE closes at AIR 65; IIT Kharagpur CSE at AIR 509; IIT Mandi CSE at AIR 3,609 |
Based on this comparison, IISc BTech is the stronger choice for candidates who prioritise research depth, access to world-class faculty and laboratories from Year 1, and the unique environment of Bengaluru's technology ecosystem. The institute's interdisciplinary structure means students interact across 40 academic departments, far exceeding the departmental exposure of a standard IIT programme.
IIT BTech remains the stronger choice for candidates who want proven, large-scale industry placement data, a wider variety of branches to choose from, or who are targeting CSE, ECE, or Mechanical Engineering specifically, which IISc does not offer at the BTech level. Candidates who would qualify for IIT Bombay, IIT Delhi, or IIT Madras CSE (AIR under 150) should still seriously consider those programmes over IISc, given the long-established placement ecosystems and global alumni networks at those specific institutes.
The ideal IISc BTech candidate: Has a JEE Advanced AIR in the range of 400 to 2,500 for Open category (depending on the programme), has a clear interest in research or interdisciplinary engineering, is open to a smaller cohort and a campus-centric environment, and wants to remain in the sciences or pursue a PhD or advanced research career after graduation. For such candidates, IISc BTech offers an educational environment that no IIT, including the top five, can fully replicate.
IISc Bangalore Joins JoSAA 2026: Conclusion
IISc Bangalore joining JoSAA 2026 is a major update for JEE Advanced candidates because students can now choose IISc BTech programmes directly during JoSAA counselling. With 125 seats across Mathematics and Computing, Aerospace Engineering, Mechanics and Computing, and Materials Science and Engineering, IISc gives research-oriented students a strong alternative to top IITs.
Students must remember that IISc BTech admission is based only on JEE Advanced 2026 rank and JoSAA counselling. No separate IISc BTech application is required. Candidates who are interested in research, Bengaluru’s academic environment, and interdisciplinary engineering should carefully add IISc choices while filling their JoSAA 2026 preference list
