What I've found to be helpful is it simply treat it like a fresh try. I don't look at the answer I gave before, I don't worry about time, I just try the problem again and make an effort to adjust my standard process to see if I missed anything. If I truly end up with the same answer again, so be it. But many times I have gotten great BR results doing it this way. I'm not only seeing what I get tripped up on, but how that led me astray and what process would help me better next time. Hope this helps you and good luck!

I could be wrong, but my interpretation of the question is that you would explain any unintended or unconventional breaks in your education. So, things like a gap year during undergrad or having to leave college prematurely due to a family emergency, things like that. A gap between undergrad and law school is common enough that they probably don't need an explanation beyond what's in your personal essays.
