This question probably sounds crazy, but I just got my scores back yesterday and I'm kinda freaked out.
Basically my situation is, to reach my goal, my overall score needs to rise by 90 points. First off, is it even possible to do this in just one month? My reading/writing is good enough, but I'm very unhappy with my math score, so I would like the increase to come from there. I'm naturally better at English than I am at math, math has always taken more practice for me. I did very little preparation when I took the test for the first time on June 3rd (I did nothing for reading/writing and a just few lessons on Kahn Academy for math -- this was no where near enough, I don't think that it helped at all) so I am looking for resources that I can use to improve my math score before I retake the on August 26th. I've been doing some research, and I've read that Kahn Academy is not the best resource because it is restricted by certain guidelines set in place by the College Board, but I really don't know if this is true. Is Kahn Academy the best preparation tool to use for math specifically, or are there any better resources out there? Books, websites, I really don't care. I just don't think I have time to sign up for classes before I retake, otherwise that's what I would be doing.
Also, this isn't my main question, but I've been wondering about it for a long time and I just remembered. I don't really know how to explain what I'm talking about though, so I'm just going to post a picture.
These are my percentiles for R/W. I don't understand why there are two of them, and what they mean. I've tried to do research before, and one of them seems to be some kind of estimate made by the College Board? Is this true, and, if so, where do they get the information from? Which one of these do colleges look at care about? I know that they have the descriptions right beside them, but I just don't understand what the difference between a "nationally representative group" and a "typical collage bound group" is. I've been confused about this since the first time I took the PSAT haha
Thanks to anyone who has actually read though all of this, or who has any advice!!
