Viva practice
Exam-style questions generated from the component library — practice like it's the real viva.
Instant feedback after every question, with worked solutions.
Every question is multiple choice with 4 options. Components you've missed before show up more often, rounds rotate through the question bank so repeats stay rare, and "All categories" rounds mix in circuit-law calculations.
What the thermal & cooling quiz asks
Questions are generated from this site’s own reference pages for the 4 thermal & cooling parts below — heatsinks, fans, peltiers — keeping the smoke in. Because each one is built from a specific field of a specific part, a wrong answer always has somewhere to send you: the component page the question came from. Nothing here is a fixed question list, so no two runs are identical.
