BITSAT 2027: Two Sessions, Pattern & 2026 Reference

BITSAT 2027: two sessions, best score counts

BITSAT — the Birla Institute of Technology and Science Admission Test — is conducted by BITS Pilani for merit-based admission to its integrated first-degree programmes at Pilani, Goa and Hyderabad: B.E. programmes across branches including Computer Science, Electrical and Electronics, Electronics and Communication, Mechanical, Chemical, Civil and newer programmes such as Mathematics and Computing and Environmental and Sustainability Engineering; B.Pharm; and M.Sc. programmes (Biological Sciences, Chemistry, Economics, Mathematics, Physics, and Semiconductor & Nano Science). BITS also runs a direct-admission route for first-rank holders of State and Central boards, but that covers a tiny cohort; nearly everyone enters through BITSAT.

The BITSAT 2027 bulletin is not out yet. Plan against the 2026 cycle, which BITS ran as two sessions: Session 1 from 15 to 17 April 2026 and Session 2 from 24 to 26 May 2026. Candidates could appear in one session or both, and the better of the two scores was taken for admission. Applications for Session 1 (or both sessions) ran from 15 December 2025 to 16 March 2026; the window for Session 2 alone reopened from 20 April to 2 May 2026. If the rhythm holds, the 2027 bulletin will appear around December 2026 on www.bitsadmission.com. Until then, any "BITSAT 2027 dates" on coaching sites are projections.

Who is eligible

Eligibility is strict on three fronts: passing year, subjects and marks. Only candidates who passed Class 12 in 2025 or will appear in 2026 were eligible for the 2026 cycle (read: only the immediate previous year and the current year — older droppers are not eligible). Expected, on the same rule, for 2027: candidates who passed in 2026 or are appearing in 2027 — the official 2027 bulletin is not out yet, and it is that document, not this expectation, that will govern — and you need Physics, Chemistry and Mathematics for B.E. and the M.Sc. programmes, or Physics, Chemistry and Biology for B.Pharm and the Environmental & Sustainability Engineering programme. English must be a compulsory subject in Class 12. The marks bar is 75% aggregate in the PCM/PCB group subjects, with at least 60% in each subject individually — theory and practical combined. BITS also revised one rule recently: students who reappeared for all Class 12 subjects in a later year are no longer eligible.

For B.Pharm, PCB students are eligible; for most engineering programmes they are not. And there is no age limit beyond the passing-year window.

Exam pattern

(The format below is the BITSAT 2026 format — the latest confirmed. BITS has not published a 2027 pattern; the 2027 bulletin will confirm or revise it.)

BITSAT is a 3-hour computer-based test of 130 multiple-choice questions: Physics 30, Chemistry 30, English Proficiency 10, Logical Reasoning 20 and Mathematics/Biology 40. Each correct answer carries +3 marks and each wrong answer costs -1, for a maximum of 390. There is a well-known quirk to the paper: if you finish all 130 questions within the time, you get 12 optional bonus questions, but attempting them locks your submitted answers for the main paper. Candidates who run out of things to check should not touch them; candidates who genuinely finish early can use them to add marks.

The two-session design is BITS's answer to the single-day luck problem. Appearing in both sessions costs a higher fee, but it buys you two measured attempts and BITS keeps the higher score. The catch is that eligibility still ends with the board marks — if your 12th aggregate is below 75%, no BITSAT score rescues you.

Fees and how to apply

For 2026, BITS raised the fee by Rs 100 across categories. Male candidates paid Rs 3,600 for one session or Rs 5,600 for both sessions; female and transgender candidates paid Rs 3,100 or Rs 4,600; candidates choosing the Dubai test centre paid Rs 7,250 or Rs 9,250. A second-session top-up for those who had already applied for Session 1 was also possible (Rs 2,000 male, Rs 1,500 female/transgender at the time of reporting). The fee is non-refundable. Applications are online only, on bitsadmission.com — BITS has no offline mode.

• Register on the BITS admission portal with your email ID and mobile number.
• Fill the application form — personal details, Class 12 academic information, programme preferences and test-city preferences.
• Upload photograph and signature in the prescribed dimensions.
• Pay the fee online and submit. Save the application number.
• Use the correction window (March for Session 1, May for Session 2 in 2026) for permitted fields.
• Book your test slot, then download the admit card and carry the printed hall ticket with a valid photo ID to the centre.

Counselling is through the BITS admission portal after results: candidates fill campus and branch preferences, and iteration-wise allotments follow the BITSAT merit, preferences and seat availability. BITSAT results are usually declared within a few days of each session, as scorecards rather than percentile tables.

Documents to keep ready

Class 10 certificate, Class 12 marksheet (final or appearing proof), caste/category documents are not needed (BITSAT has no caste reservation, unlike state CETs — admissions are merit-only, a point people carry over incorrectly from other exams), board-toppers seeking direct admission need the official topper certificate from their board, a recent photograph and signature in the prescribed formats, and the hall ticket plus photo ID for the test day.

Common mistakes

Paying the fee and then discovering the 75%-aggregate rule on the day of the result; treating the -1 negative marking as if guessing were free and over-attempting (BITSAT has carried a −1 penalty throughout recent cycles); assuming Session 2 alone is cheaper (it is, but Session 1 practice data is lost); and skipping the mock tests BITS provides on the admission portal — the English Proficiency and Logical Reasoning sections have a different feel from JEE-style papers and reward familiarity.
