I am having trouble finding sample essays for their 250 word essay. Can anyone find a link to a site?

Does the negation of the right answer choice for a NA question have to completely destroy the argument or can it merely weaken?

I've been drilling questions for LR, and I just let the 7sage system decide what questions to pick for me. I was wondering if the way the drill chooses what questions to recommend for a future drill is by 1) adding more questions of the type I have answered wrong and 2) adding more questions of the type I have spent a long time on. I feel like I see a lot of the same questions types (weaken, parallel flaw, etc) and I just wanted to make sure that it's not because the system is just giving me more questions that I spend a lot of time on. I just worry if I am not getting enough practice with the other question types. I know I can just drill by type, but I would rather have a mix that the system chooses.

I'm new to drilling. I was wondering if anyone has any advice on how to drill? How many questions should I start with, time or untimed, etc. Any advice is appreciated!

Not sure if this matters, but I got a 151, 151, and 160 on PTs. I won't be taking more PTs until I start drilling. Thanks!

Edit: I am nearly done with 7Sage's cirriculum

Edit: So I just finished drilling 5 questions, and I got 3 correct, but I got all five correct during blind review. Would the next step be to analyze each question/just the questions I had trouble with and then do extensive reasoning on my thought process for each question? I know spending time is necessary, but I'm just not sure what the most time-efficient way of doing this would be. any advice is appreciated!
