CONNECT THE FUNDAMENTALS
What to practise.
Trace the complete measurement chain from the physical quantity to the indicated output. Practise sensors, bridge circuits, signal conditioning and control with clear reference conventions. Review sensitivity, accuracy and resolution as different ideas, and identify which errors or loading effects the question includes in its instrument model.
- Measurements
- Sensors
- Analog and digital circuits
- Control systems
These areas help organise revision. Check the official syllabus for complete requirements; older papers follow their own printed instructions.

02 / Practise
Work through a subject area and keep notes on the steps you missed. Include general aptitude in your revision.
03 / Simulate
Attempt a complete paper against the clock. Review the answers and marking rules before choosing what to revise next.
Before you start.
Can I study without starting the timer?
Yes. Choose Study to browse questions and worked solutions. Attempt opens the exam workspace; the timer starts after the quiz content is ready.
Which marking rules apply?
Use the instructions on each paper. Question types and penalties vary by year. Historical linked-answer pairs require the first answer to be correct before the second can earn marks. Common-data questions are scored independently.
Are all GATE years and branches available?
The library is growing. Only the papers listed above are published; a branch guide does not mean its full archive is available.
Independent preparation resources. OneNoughtOne is not affiliated with the GATE organising institutes.
