Let me look at the structure of each file to understand how questions/topics are organized.

Good, question splitting matches counts exactly. Now let's classify each question into MSK topics using keyword matching.

Key takeaways — Most important (highest-yield) topics across all 5 years

1. Upper Limb Anatomy — the single most tested area every single year (109/437 = ~25%)
  • Shoulder & brachial plexus (rotator cuff muscles, quadrangular space, axillary/posterior circumflex vessels) is consistently the biggest subtopic (~56 MCQs total, present every year, 9-11 questions/paper).
  • Forearm & wrist (radius/ulna, anatomical snuffbox, pronation/supination) is the second-biggest upper limb subtopic (39 MCQs).
  • This region never drops below 6 MCQs in any paper — it's a guaranteed high-weightage area.
2. Muscle physiology/histology + neuromuscular pharmacology — second most important (87 MCQs)
  • Sharply increasing trend: only 14 in 2020 but jumped to 20-23 in 2021 and both 2024 papers. This is now one of the highest-yield areas in recent papers.
  • Sub-focus: contraction mechanics (isotonic/isometric), NMJ blockers (succinylcholine, atracurium, rocuronium), acetylcholine physiology.
3. Lower Limb Anatomy — third most important (78 MCQs)
  • Very heavily tested in 2020 (24 MCQs — the peak) but fell sharply in 2021-2023 (only 3-7 MCQs), then rebounded strongly in both 2024 papers (21 and 18 MCQs). Thigh/knee and leg/ankle are the dominant subtopics.
4. Notable year-specific spikes worth flagging:
  • 2021: Gout & anti-gout pharmacology exploded to 13 MCQs (vs. 1-5 in other years) — almost every antigout drug (allopurinol, colchicine, probenecid, febuxostat) was tested repeatedly that year.
  • 2024 (both papers): Biochemistry (GAGs, collagen, glycogen metabolism, minerals like zinc/copper/Wilson's disease) rose sharply — 11 and 6 MCQs respectively, far above prior years (1-4). This signals a broadening of the exam beyond pure gross anatomy into biochemistry integration.
  • 2024: Vitamins/calcium metabolism also spiked (6 MCQs in each 2024 paper vs. 0-2 before).
  • 2023 is the outlier: only 24 total MCQs (much shorter test), with unusually high relative weight on bone histology/growth (5/24) and low representation of muscle physiology — likely a shorter/partial module test rather than a full-length one.

Practical exam-prep priority ranking

  1. Upper limb anatomy (especially shoulder/brachial plexus and forearm/wrist) - highest and most consistent yield every year
  2. Muscle physiology & NMJ pharmacology - rapidly growing weightage, especially in 2024
  3. Lower limb anatomy (thigh/knee, leg/ankle) - historically huge (2020) and resurging in 2024
  4. Embryology of the limb (germ layers, teratogenic periods) - stable ~5-6 MCQs almost every year, easy consistent marks
  5. Bone histology/growth & joint histology - steady presence (3-5 MCQs/year), low-effort high-return topics
  6. Biochemistry integration (GAGs, collagen, glycogen storage, minerals) and vitamins/calcium - increasingly important in the newest (2024) papers, worth extra attention if preparing for an upcoming exam, since the trend suggests continued emphasis
  7. Gout pharmacology - watch for recurrence since it was a major 2021 focus that could resurface
If you want, I can also pull out the exact question list per topic per year (e.g., all shoulder/brachial plexus questions from 2020-2024) so you can revise from the actual repeated questions.
