AMC CAT MCQ Examination: What to Expect + Practice Questions
Wondering what to actually expect on the AMC CAT MCQ exam? Here's the real exam format straight from the AMC's own site, plus four full-length practice questions in that exact single-best-answer style — each with the correct answer and a full explanation.
The AMC CAT MCQ exam consists of 150 multiple-choice items, each a single-best-answer question with five response options, completed in 3.5 hours in a single session. Content spans three real areas the AMC's own materials name explicitly: disease process, clinical examination and diagnosis, and investigation, therapy and management. AMC states candidates are expected to complete all 150 scored items.
Below are four practice questions in that same five-option, single-best-answer format — TopQbank's own original items, not real past AMC questions (the AMC does not publish a retired-question bank; its own free official prep resource is the eMedici MCQ Preparation App).
Question 1
A 58-year-old man presents with sudden-onset severe epigastric pain radiating to the back, associated with nausea and vomiting. He has a history of heavy alcohol use. Lipase is elevated at 5 times the upper limit of normal. What is the most appropriate initial investigation to assess severity?
A) Abdominal X-ray
B) Contrast-enhanced CT abdomen immediately
C) Clinical and laboratory severity scoring (e.g., using validated criteria) with supportive management
D) Upper GI endoscopy
Correct answer: C) Clinical and laboratory severity scoring with supportive management. Acute pancreatitis is diagnosed clinically here (typical pain plus lipase > 3x ULN), so further imaging isn't needed to confirm the diagnosis. Initial management is supportive (IV fluids, analgesia, monitoring) with severity assessed via validated clinical/lab scoring systems. Contrast CT is reserved for diagnostic uncertainty or to assess complications (e.g., necrosis) typically after 72 hours if the patient isn't improving, not as the immediate initial step.
Question 2
A 34-year-old woman presents with fatigue, weight gain, cold intolerance, and constipation over several months. TSH is markedly elevated with a low free T4. What is the most appropriate management?
A) Levothyroxine replacement
B) Radioactive iodine ablation
C) Carbimazole
D) Observation and repeat testing in 6 months
Correct answer: A) Levothyroxine replacement. This presentation and biochemistry (high TSH, low free T4) confirm primary hypothyroidism, and the standard treatment is levothyroxine replacement therapy, titrated to normalize TSH. Radioactive iodine and carbimazole are treatments for hyperthyroidism, not hypothyroidism, and observation alone would leave a symptomatic, biochemically confirmed condition untreated.
Question 3
A 45-year-old woman presents with a 2-week history of a painful, swollen right calf following a long-haul flight. Examination reveals calf tenderness and mild swelling. What is the most appropriate initial investigation?
A) D-dimer if clinical probability is low, otherwise proceed directly to compression ultrasound
B) Chest X-ray
C) MRI of the leg
D) Empirical anticoagulation without further investigation
Correct answer: A) D-dimer if clinical probability is low, otherwise proceed directly to compression ultrasound. This presentation raises suspicion for deep vein thrombosis. Standard practice uses a validated clinical probability assessment: if probability is low, a negative D-dimer can reasonably exclude DVT; if probability is moderate-to-high, proceed directly to compression ultrasound rather than relying on D-dimer alone, since a positive D-dimer is nonspecific. Empirical anticoagulation without objective confirmation is not standard first-line practice when timely imaging is available.
Question 4
A 6-year-old boy presents with a 1-day history of right-sided testicular pain and swelling, with an absent cremasteric reflex on the right. Onset was sudden while playing. What is the most appropriate immediate management?
A) Reassurance and review in 48 hours
B) Urgent urology referral for surgical exploration
C) Scrotal ultrasound, with surgery deferred until results are available regardless of clinical suspicion
D) Oral antibiotics for presumed epididymitis
Correct answer: B) Urgent urology referral for surgical exploration. Sudden-onset testicular pain with an absent cremasteric reflex is highly suspicious for testicular torsion, a surgical emergency where testicular viability depends on time to detorsion (ideally within 6 hours of symptom onset). Management should not be delayed for imaging when clinical suspicion is high — urgent surgical exploration is the appropriate immediate step, not empirical antibiotics (which would be appropriate for epididymitis, a key differential, but not while torsion cannot be excluded) or a delayed review.
Study takeaway: with 150 questions in 3.5 hours — about 84 seconds a question — and content spanning disease process, clinical examination/diagnosis, and investigation/therapy/management in roughly equal real emphasis per AMC's own framing, practice recognizing time-critical presentations quickly (like testicular torsion or tension-pneumothorax-style emergencies) so those don't eat into time better spent on more nuanced management questions.
