Frequently Asked Questions
What is the GATE BM 2026 exam pattern?
GATE Biomedical Engineering 2026 is a 3-hour computer-based test with 65 questions worth 100 marks. The paper combines 15 marks of General Aptitude, 13 marks of Engineering Mathematics, and 72 marks of subject questions spanning Electrical Circuits, Signals and Systems, Electronics, Measurements and Control, Sensors and Bioinstrumentation, Anatomy and Physiology, Medical Imaging, Biomechanics and Biomaterials. Questions are MCQ, MSQ (multiple-select) or NAT (numerical answer type).
What is the marking scheme and negative marking in GATE BM?
MCQs carry 1 or 2 marks with negative marking of 1/3 or 2/3 respectively for a wrong answer. Multiple Select Questions (MSQ) and Numerical Answer Type (NAT) questions carry 1 or 2 marks with no negative marking — but partial credit on MSQ is not given. Unanswered questions earn zero.
Who conducts GATE 2026 and how do I register?
GATE 2026 is conducted by IIT Guwahati on behalf of the National Coordination Board GATE (NCB-GATE), MoE. Registration is done through the GOAPS portal on gate2026.iitg.ac.in, with an application window that opens in late August and closes in early October 2025, an extended (surcharge) window thereafter, and the BM exam scheduled for February 2026.
Which sections carry the highest weightage in GATE BM?
Biomaterials and Biomechanics together (roughly 15–18%), Medical Imaging and Instrumentation (roughly 15–18%), and Signals and Systems (roughly 12–15%) are typically the heaviest scoring areas. Engineering Mathematics (13 marks), Electrical Circuits, Analog and Digital Electronics, and Sensors and Bioinstrumentation are also high-yield, so a balanced core preparation is essential.
What is the GATE BM syllabus weightage between sections?
General Aptitude is 15 marks and Engineering Mathematics is 13 marks (28 marks combined). The remaining 72 marks are distributed across the 10 core BM sections — Electrical Circuits, Signals and Systems, Analog and Digital Electronics, Measurements and Control Systems, Sensors and Bioinstrumentation, Human Anatomy and Physiology, Medical Imaging Systems, Biomechanics and Biomaterials. Exact weightages vary slightly each year.
Is GATE BM useful for jobs and how long is the score valid?
Yes. GATE BM scores support M.Tech/PhD admissions at IITs, IISc and NITs, fellowships, and recruitment in research labs, medical-device companies and some PSUs that recruit instrumentation/biomedical profiles. The GATE 2026 score is valid for 3 years from the date of result announcement for admissions and recruitment.
Can I use a calculator in GATE BM?
Yes — but only the virtual scientific calculator provided on-screen in the GATE CBT interface. Physical calculators, mobile phones, smart watches, and any digital aids are strictly prohibited. Practising with the official online virtual calculator (available on the GATE website) ahead of the exam is highly recommended.
