Why Argonaut

Built to move your score. Priced so you can afford it.

Our whole job is getting you the score you want: a Step 1 pass you never had to sweat, a Step 2 CK score you're proud of. Here's how.

01

Questions that feel like the real exam.

Every question is written the way the real exam writes them: a full patient case, one best answer, no trick wording. Practice that looks like test day is practice that carries over to test day.

You also get an explanation for every answer choice, not just the right one, so you learn why the other four are wrong. That is usually where the points are hiding.

  • Full clinical vignettes with one best answer
  • Mapped to the official USMLE content outline
  • All five choices explained, not just the right one
  • Test-day screen: timer, lab values, highlighter, strike-out
02

ARGO finds your weak spots. Then it fixes them.

ARGO is our algorithm. It records 16 data points on every answer you give: how long you took, how sure you were, whether you talked yourself out of the right answer, which wrong option pulled you in, how long since you last saw the topic, and more.

Over time that adds up to a precise picture of where you lose points. ARGO ranks your weak spots and builds your next session around the worst one. When it closes, ARGO moves on to the next.

Numbers don't lie. Put the reps in, and not improving becomes very hard to do.

Item 12 of 40
Lab values
47:18

A 63-year-old man comes to the office because of difficulty rising from a chair and climbing stairs for 3 months. He has smoked two packs of cigarettes daily for 40 years. After 10 seconds of sustained contraction, the patellar reflex becomes brisker and strength transiently improves.

Which of the following is the most likely mechanism of this patient's weakness?

  • AAntibodies against muscle-specific kinase
  • BAntibodies against postsynaptic acetylcholine receptors
  • CAntibodies against presynaptic calcium channels
  • DDegeneration of upper and lower motor neurons
  • EToxin-mediated cleavage of SNARE proteins

Nuggets

Gold means the exam loves it.

The facts that come up again and again are marked gold. Collect them as you go, and see which classics you've nailed and which still catch you out.

AQ-1035 · Endocrine · PhysiologyNugget

PTH is inappropriately normal, so the hypercalcemia is PTH-dependent. The deciding clue is the kidney: urinary calcium is low with a calcium/creatinine clearance ratio of 0.006.

Nugget

Hypercalcemia + low urine calcium = FHH, not an adenoma

Desensitized calcium-sensing receptors reset the set point: PTH stays normal and urine calcium is low. It is benign; do not send the patient for parathyroidectomy.
