Really impressed by the multi-model planning and code review. Having different models collaborate instead of relying on just one actually leads to better decisions. You can feel the difference on more complex tasks.

Pretty good, I like the process. I did run into a couple questions that were worded weirdly or just had odd answer logic (it'll mark you wrong for the tiniest typo). Would be cool if it had a bit more wiggle room or a way to flag those. But still, definitely helpful.
