Hi, I am looking for someone to study with in Seoul.
I am scoring around mid-high 160 (from 165 to 169), sort of in plateau there and want to break above it.
I live in Mangwon (near Hongdae, Hapjeong, Sinchon).
I work full time and mostly study early in the morning during the week days but could be available for study in the evening. Also am available most of the weekends. Looking for someone to do PTs and BR together on a similar pace.
Planning to sit for the June exam (sort of bombed the Jan one) and aiming for 173-4.
Let me know if anyone's around.

How do we know when to use contrapositive and when not to when we see a conditional logic? Here, if we just graph the conditional logic of the anthropologists' argument as written in the stimulus, it would go ((not evolved the ability to cope --> not survive)). yes I get it that in this case, intuition tells us what anthropologists meant to say is the contrapositive of that, which is ((survive-->evolved the ability to cope)). And yes, based on this contrapositive derived from our "intuition," because the next sentence goes: ((Australoptithecus coped-->not survived)), A is correct that the author confuses nec. condition with suf. condition. However, if you could not figure out this contrapositive because your intuition does not tell you to do so, then the flaw of the statement Australo cope-->not survive is not confusing suf condition and nec condition but rather something like...mistakenly negating suf. condition...or something like that...
I guess what I am wondering is, how do you know when is correct to use contrapositive of the conditional logic of a statement and when not to? (other than "intuition")?
I hope this makes sense...
