I heard the question style for the COMLEX is a bit different. Can anyone outline some differences?
COMLEX vs. USMLE
1. The USMLE may have A-J options; the COMLEX will only have A-E. The USMLE likes to eliminate all guesswork involved by providing opposites of all distractors and correct answers.
2. Question stems may include osteopathic structural examination findings, most commonly viscerosomatic/Chapman's relationships, which may seemingly be the only indication for an answer choice.
3. The USMLE has more basic laboratory techniques (gel electrophoresis, genetic interpretation) and
hard basic sciences like biochemistry pathways than the COMLEX.
4. The COMLEX tends to use pathognomonic, 'classic', findings presented in such a way that you have difficulty recognizing that it's right in front of you. This is a bad example, but they will not say "positive Babinski sign" but rather "extension of the great toe upon plantar stimulation."
5. The COMLEX wants to know 'what is the most likely' while the USMLE often asks for associations in attempt to make them third order.
6. The COMLEX generally has shorter question stems and has about 50% multiple-part (one stem with two questions) question types with some matching. There is more randomness to the COMLEX with sometimes questions being a single sentence and other times taking up half the page. The USMLE mostly has single questions with longer stems; sometimes it may be better to read the question and gloss over the answer choices before delving into the question stem.
7. As for images there is more histology on the USMLE (see #3).
8. The USMLE will provide more theoretical situations (e.g., a researcher wants to know XYZ) than the COMLEX, which seemingly has none. The COMLEX is more about patient presentations.
