About GATE

GATE (Graduate Aptitude Test in Engineering) is the premier national-level examination for admission to M.Tech, M.E., and PhD programs at IITs, NITs, IISc, and other premier institutions in India. GATE scores are also used by Public Sector Undertakings (PSUs) like ONGC, BHEL, NTPC, IOCL, and DRDO for graduate trainee recruitment. Conducted by IITs and IISc on a rotational basis, GATE is considered one of the most challenging and prestigious engineering examinations in India.

Question Types:
- MCQ (Multiple Choice Questions): 1-mark and 2-mark questions
- MSQ (Multiple Select Questions): No options to select; choose all correct options
- NAT (Numerical Answer Type): Enter numerical value using virtual keypad

Negative Marking:
- 1/3 mark deducted for each wrong 1-mark MCQ
- 2/3 mark deducted for each wrong 2-mark MCQ
- No negative marking for MSQ and NAT questions
