2. Salary and perks comparison (approximate, based on BPS-16 to BPS-18)

| Component | FIA | NAB | ANF | |-----------|-----|-----|-----| | Basic pay (BPS-16) | PKR 30,000–40,000 | PKR 35,000–45,000 | PKR 28,000–38,000 | | Allowances (total) | 100%–150% of basic (including risk, special duty, and technical allowances) | 80%–120% (including performance and field allowances) | 90%–130% (hardship, risk, and uniform allowances) | | Gross monthly (entry-level) | PKR 60,000–80,000 | PKR 65,000–85,000 | PKR 55,000–75,000 | | Perks | Housing, medical, vehicle, free travel, children’s education allowance, pension | Official residence, medical, vehicle, performance bonuses, pension | Housing, medical, uniform allowance, free travel, pension | | Promotion speed | Moderate (5–7 years to next grade) | Fast (3–5 years, due to rapid expansion) | Slow (7–10 years) | | Posting | Mostly urban centers | All over Pakistan | Border areas, high-risk zones |

3. Syllabus difficulty comparison

| Aspect | FIA | NAB | ANF | |--------|-----|-----|-----| | Written exam subjects | General Knowledge, English, Urdu, Pakistan Studies, Islamic Studies, Current Affairs, and optional (e.g., Law, Criminology) | English, General Knowledge, Pakistan Studies, Islamic Studies, and subject-specific (e.g., Law, Economics) | English, General Knowledge, Pakistan Studies, Islamic Studies, and optional (e.g., Chemistry, Pharmacology) | | Difficulty level | Moderate to High (vast syllabus, analytical questions) | High (complex legal concepts, case studies) | Moderate (technical for science subjects, general for others) | | MCQs vs subjective | 60% MCQs, 40% subjective | 50% MCQs, 50% subjective | 70% MCQs, 30% subjective | | Physical test | Yes (running, push-ups, etc.) | No physical test (only medical) | Yes (rigorous physical endurance) | | Interview | Panel of 3–5 members, focus on current affairs and law | Panel of 3 members, focus on ethics and corruption | Panel of 3 members, focus on drug-related issues | | Preparation time needed | 6–8 months | 8–12 months | 4–6 months |

4. Key differences in exam pattern

  • FIA: Questions often involve analytical reasoning and interpretation of laws (e.g., PPC, CrPC). Current affairs are heavily tested.
  • NAB: Emphasizes legal reasoning, case studies on corruption, and knowledge of NAB Ordinance 1999. High weightage on ethics.
  • ANF: Technical subjects (Chemistry, Pharmacology) for science graduates; general subjects for others. Physical test is mandatory and challenging.

Common mistakes to avoid

  1. Ignoring the physical test for ANF – Many aspirants focus only on written exams but fail the running or endurance test. Always practice physical fitness alongside studies.
  2. Choosing an agency solely for salary – NAB offers higher pay but requires deep legal knowledge. If you dislike law, FIA or ANF might be better.
  3. Underestimating current affairs for FIA – FIA’s exam heavily relies on national and international news. Neglecting this leads to low scores.
  4. Overlooking interview preparation – All three agencies have panel interviews. Practice common questions and ethics scenarios.
  5. Not checking eligibility criteria – Age limits, domicile, and educational requirements differ. For example, ANF prefers science graduates for certain posts.
  6. Using outdated syllabus – Each agency updates its syllabus periodically. Always download the latest from official websites.
  7. Neglecting optional subjects – Choosing an optional that doesn’t align with the agency’s focus (e.g., selecting Botany for NAB) wastes preparation time.

Practical study plan
