CSS Optional Subjects Group II past papers cover the six science and mathematics subjects candidates can choose from when picking their Group II optional, each set as a single 100-mark paper rather than the two-paper format used in Group I. This page is the central archive for CSS Bureau's Group II collection: Physics, Chemistry, Pure Mathematics, Applied Mathematics, Statistics, and Geology, each with papers from 2016 through 2026.

How the Group II subjects compare
Every Group II subject carries the same 100 marks and the same three-hour format, but each paper selects its questions differently, and the subject matter itself ranges from abstract mathematics to applied earth science. Knowing the selection rule in advance matters just as much as knowing the syllabus.
| Subject | Question format | Best suited to |
|---|---|---|
| Physics | 20-mark MCQs, then attempt 4 of 80-mark written questions | Candidates with a physics or engineering background |
| Chemistry | 20-mark MCQs, then attempt 4 of 80-mark written questions | Candidates with a chemistry or applied-science background |
| Pure Mathematics | Five questions: two from Section A, two from Section B, one from Section C | Candidates confident with proof-based, abstract mathematics |
| Applied Mathematics | Attempt 5 of 8 questions, no fixed sections | Candidates who prefer applied, formula-driven problem solving |
| Statistics | 20-mark MCQs, then two questions from each of two 80-mark sections | Candidates with a statistics, data, or research background |
| Geology | 20-mark MCQs, then two questions from each of two 80-mark sections | Candidates with an earth-science or geology background |

Frequently asked questions
What subjects are in CSS Optional Group II?
Group II contains six subjects: Physics, Chemistry, Pure Mathematics, Applied Mathematics, Statistics, and Geology. Candidates choose one subject from this group, each carrying 100 marks.
Is Group II the same 200-mark format as Group I?
No. Group I subjects like Economics and Political Science are split into two 100-mark papers for a 200-mark total. Every Group II subject is a single 100-mark, three-hour paper.
Which Group II subject is easiest for CSS?
There's no universally easiest subject. Physics, Chemistry, Statistics, and Geology combine MCQs with written questions and reward strong recall and clear explanation, while Pure Mathematics and Applied Mathematics are proof and formula-driven with no MCQ section. The subject that matches your academic background is usually the strongest choice.
Can I choose more than one Group II subject?
No. Candidates select one subject from Group II as part of their overall optional subject combination, alongside choices from the other optional groups.
Where can I download authentic Group II past papers?
Every subject page linked above sources its papers from FPSC's official published question papers, checked for their printed marks, time limits, and paper instructions. You can also confirm recent years yourself on the official FPSC Previous Question Papers section.
Source and verification
Papers across every subject on this page are compiled from FPSC's official published question papers. Where a specific year was no longer available on FPSC's own site, it was cross-checked against independent archives before being added, so you can rely on this archive as an accurate representation of the original exams.
