How This Section Fits Your Prep

Everyday Science questions in PPSC papers rarely go beyond secondary-school-level science — the difficulty is in breadth, not depth, since any general-science fact is fair game. Repetition across a large question pool is what closes the gaps a single revision pass misses.

HighYield's PPSC question bank covers Everyday Science alongside General Knowledge, Pakistan Studies, Islamiyat, English, Urdu, Geography, General Maths, Current Affairs, Basic Computer and Ethics & Civics — every question explained.
