Hi Antal,
Thanks for the question! My preference is to immediately review every question, including the ones you answered correctly. this is because in the immediate aftermath of seeing a question, you are best positioned to identify exactly what you did the first time you saw the question, which is the situation you will be in during your actual LSAT.
Then, a few days later, take a look at the problem again. This is because, as I mentioned
in a blog for students retaking the LSAT, "most questions are so well-constructed that students miss a lot of the nuances on their first read of the question. Re-reading the questions alone will help you better understand all of the pieces of the argument, and better acquaint you with the way the questions are constructed."
Please let me know if that helps. Thanks!
