This advice might be too little too late for those of you next week, but if it can be helpful for anyone...
I have been struggling mightily with confidence and have seen my scores dip significantly in the past couple of weeks. Part of the struggle is due to the fact that the last time I sat for the test, I massively underperformed and was miserable over my score. So miserable that I swore off the LSAT/law school for several years.
Once I got back into prep, I decided that I was going to save that PT for right before the test to prove to myself that I was much better prepared, could do this, blah, blah, blah. I hadn't looked at the PT since getting my score back so it was essentially fresh. (Did I mention that I swore off the test for so long that my original score is no longer on the record? (Gross I'm old/thank goodness.))
Long story short, I went from a 160 to a 176, and was one question away from a 180 in BR.
I say this not as a humble brag (ok, maybe a little bit of that) but because I have more confidence now than I've had at any point in my prep. I think a huge mental hurdle for retakers is the fact that you KNOW it can go sub-optimally. But by taking the one that originally got the best of you...well, you get what I'm saying.
(Also, major props to 7Sage because even if I hadn't underperformed as much as I did, I still wouldn't be close to the level I'm at now.)
Full disclosure: The beam makes sense to me. And I kind of think of a good weakening answer choice as a shield that deflects part of the beam and bounces it back, so that part of the relationship between the premise and conclusion can still stand, but it will be less effective. And as soon as this is cleared up, I'm confident I'll be able to move on with my life and do just that.
But I am curious as to why we can't attack the premise or the conclusion. Earlier in the course, we defined an argument as "premise plus conclusion." So technically, if we take down any one element, aren't we weakening the argument?
I get that simply negating the conclusion can sound petty, and if unsupported, doesn't have any logical legs to stand on. But if an answer choice attacks the conclusion with additional evidence, doesn't that weaken the argument, since the conclusion is part of the argument?
