@Harry Styles I think the only inference we can make from negating most statements are like the following:

If A -m-> B, then all A cannot be not B i.e. A->/B (and the contrapositive all B cannot be not A).

That's the only thing we can infer i believe

This is kinda related to what I am struggling with. I am finished with the core curriculum and have started doing the practice blocks. I already put the lowest hour amount (1-2 hours per day) because of work schedule — which I do have 1-2 hours free everyday. However, to do 2-3 drills and a practice section every day and blind review within 1-2 hours is kind of crazy. Maybe its just me - but one section takes about an hour and a half for taking the section => blind review + explanations of thinking within blind review => checking my answers and reviewing the ones i got wrong.

A drill of 5-6 LR questions w/ blind review is sometimes doable I think with a section within 1-2 hours, but 2 passages + blind review + post-blind review could easily take an hour of time.

It really is a regressive system because if you struggle and get a lot wrong, then it takes longer to do the blind review and post review because you have more questions to review in general.
