Hello 7sagers

I have recently finished the CC and also took another diagnostic. Turns out I need more practice on LR sections and LG. With LG I am trying to fool proof some test. But for LR How do you reccomend practicing at this point? Should I just pull LR sections starting from the first PT?

Also, some have reccomended starting in the 50's practice tests as the other tests are older and different - any thoughts on that?

Thanks a lot.
