Gate-linked prep notes (2026)

For PSU-style hiring, candidates often combine GATE fundamentals with company aptitude/technical screens:

1. Revise core branch subjects (not only coding)
2. Practice numerical aptitude at campus-placement speed
3. Revisit previous technical MCQs on this site
4. Keep document readiness (gate scorecard if applicable, marksheets)

Extra technical drill

Q: Why do many PSU drives still test engineering fundamentals heavily?

Roles are often engineering-core, not pure software-product SDE. Expect thermodynamics / power systems / electronics / strength of materials style depth depending on your discipline, plus aptitude.

Q: Should CSE students ignore GATE topics for BHEL?

Not entirely. OS, DBMS, networks, and DSA still appear in technical rounds. Pair them with the aptitude mock on this site.
