You got a question wrong, but the explanation doesn't click. Or you guessed right and want to know why. Either way, you're stuck.

Practice questions now have detailed walkthroughs that explain the reasoning behind each answer. Not just "here's the correct answer" — actual breakdowns of why wrong answers don't work and how to think through similar questions next time.

This is a paid feature. If you're working through practice sets and want to actually understand what you're missing (not just memorize answers), these walkthroughs help.
