I think the biggest variable here is everyone's definition of “doing MCQs”. Off the top of my head, here's 5 popular approaches I've seen on here:
1. Taking note on MCQs: answer MCQ (30 seconds – 1.5 minutes, depending on complexity, maybe longer for intense calculations), then 1-3 minutes for taking notes
2. Researching for answers on MCQs: 1-3 minutes looking in textbook (could be longer, depending on your familiarity with the book), answer MCQ (same as above)
3. Research for answers and taking notes on MCQs: 1-3 minutes looking in textbook, answer MCQ, then 1-3 minutes for taking notes
4. Reading provided explanation(s) but not reading or taking notes outside of that: answer MCQ, then 30 seconds – 1 minute to read answer provided
5. Just answering MCqs: answer MCQ (still same as above – 30 seconds – 1.5 minutes, maybe longer for complex)
Time to do 200 MCQs under each scenario:
1: 8.33 hours
2: 8.33 hours
3: 16.66 hours
4: 5.83 hours
5: 3.33 hours
So, especially when you add variation for how quickly or slowly people approach MCQs, how quickly or slowly they teach notes, how quickly or slowly they research, etc., you can see why a person's definition of “doing MCQs” as well as their speed makes a big difference in what they can accomplish count-wise per day. My approach was basically #4. I'd occasionally Google something if I knew I was clueless on the topic, but I never used the textbook while doing MCQs, and avoided any sort of research while doing MCQs since I was trying to use memory. I'd read the answer provided, but sometimes I'd go more towards #5 – if I'd known the right answer, without hesitation, then I didn't bother reading the explanation. So, I'd say I was #4 80-90% of the time and #5 10-20% of the time. This would mean that my number of MCQs I could do per day would be a lot more than someone following #3, but that doesn't necessarily mean I'm doing any “more” or “better” than them. Whichever way they or I learn best is the best way for they or me to study, regardless of how many MCQs are done as a result.
Note: I never did repeat questions. Always intended to, never got that far. So, my times above are based on estimates for first-time questions. Sure, repeat questions you might be able to answer in 10 seconds cause you recognize the question, but that's not learning at all (recognizing the question isn't learning the material to help on exam day!) and not as easy to gauge. Also, I did all my MCQs after reading the whole book, so no topics were “new”, but they were “unpolished”.
