(It's possible this is doable, and I just cannot figure out how to do it).
After finishing a prep test, it seems you can either review the whole test or filter and look at specific questions. When you click into that question, and then go back, you lose the filter criteria. It would be nice if these two were combined and you could review a batch based on filter criteria.
My specific use case is: looking at questions where I consumed much more than the target amount of time. Most of this platform seems to be geared towards correct vs. incorrect. In my opinion, this is only part of the puzzle. Questions you get correct, but that take up a disproportionate amount of your exam time, are also worthy of review.
Sufficient assumptions are what they sound like. What is the assumption that is sufficient for your conclusion to follow from your premises? In other words, what is something that if true, when combined with the other premises being true would guarantee a true conclusion.
Take the argument:
Garfield is a housecat
All housecats are pets
All pets are cute
Therefore, Garfield is cute
If the argument was missing any one of the premises, adding it back would be "sufficient" to fix it. If premise #2 was missing, adding it back is "filling the gaps" as you said. If premise #3 is missing it is "linked to the conclusion" as you said. Importantly, premise #1 could also be missing or you could jump over premises entirely. A sufficient assumption would also be "garfield is cute" (skipping past the whole argument but guaranteeing the truth of the conclusion if true).
