Introduction
Everyday Science is one of the most dependable scoring areas in Pakistan’s competitive exams. Whether you are sitting for an FPSC screening test, a PPSC recruitment paper, an NTS test, or the CSS and PMS compulsory papers, science questions appear in nearly every syllabus. In 1-Paper exams and screening tests, where every mark counts toward the merit list, these questions can separate selected candidates from those who just miss out.
The good news is that Everyday Science is based on standard textbook facts. Vitamins and their deficiency diseases, blood cells, the layers of the atmosphere, chemical names and the solar system are asked again and again, often with only the options changed. Practising repeated questions helps you answer in seconds and save time for harder sections.
This guide from MCQsDesk brings you 20 high-yield MCQs, split into Biological Sciences and Physical Sciences. Read each answer, then try to remember the fact behind it.

Section 3: Essential Tips to Master Everyday Science MCQs for 2026
1. Learn Topic by Topic
Divide the subject into clear blocks: vitamins, blood and circulation, human organs, chemistry basics, atmosphere, energy, and astronomy. Finish one block before starting the next.
2. Make Quick-Reference Tables
Tables are the fastest way to revise. Useful ones include:
- Vitamins, their sources and deficiency diseases
- Common chemical names and formulas
- Atmospheric layers in order
- Planets in order from the Sun
3. Use Memory Tricks
Mnemonics help with lists. For example, remember the atmosphere from bottom to top as Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere.
4. Focus on Units and Formulas
SI units (Newton, Joule, Watt, Pascal) and basic formulas are asked frequently and are easy marks once memorised.
5. Solve Past Papers of Multiple Commissions
FPSC, PPSC, NTS and others often repeat the same science facts. Solving papers from different commissions exposes you to more variations of the same question.
6. Understand, Do Not Just Cram
If you know why a vitamin deficiency causes a disease, you can answer reworded questions with confidence. Concept clarity beats rote learning.
7. Practise Timed Sets
Attempt 20 to 25 MCQs in a fixed time. If negative marking applies, skip questions you are truly unsure about.
8. Revise Regularly
Revisit your notes within 24 hours, then after a week, then after a month. Spaced revision keeps facts in long-term memory.
Conclusion
Everyday Science rewards candidates who revise steadily rather than those who cram at the last minute. The 20 MCQs above cover facts that appear again and again in FPSC, PPSC, NTS, CSS and PMS papers, so they make a strong foundation for your preparation.
Practise daily on MCQsDesk for fresh solved MCQs and past paper practice. If this guide helped you, share it with your fellow aspirants so everyone can prepare smarter together.
Best of luck with your exam preparation!
