About these questions Every problem below is authored by BlinkNBuild at GATE standard and solved in full. They are practice problems, not reproductions of any past paper - when a question is a genuine PYQ we say so explicitly and name the year and the official answer key it was checked against. We would rather label honestly than claim a provenance we cannot prove.

How to use this portal

StepWhat to doWhy
1 Attempt the question before revealing anything Active recall beats re-reading. Picking an option locks in your answer so you find out whether you were right, not whether it looks familiar
2 Reveal and read every step, even the ones you think you know Most lost marks are arithmetic and unit slips, not concepts. The steps are written out so you can find exactly where you diverged
3 Read the common trap on every question Each one names the specific wrong answer the question is built to produce. That is usually the option you nearly picked
4 Come back a week later and redo it cold Your progress is stored in this browser, so you can see which ones you have actually got right
Studying Digital Circuits for GATE? The Verilog & SystemVerilog masterclass covers the same syllabus far more deeply than any GATE book - sequential design, FSMs and setup/hold analysis are all worth a read before you attempt the Digital section.
