For my school at least, when I clicked to request a transcript it sent me to the actual portal on my schools page to purchase and send a transcript. Did you do anything along those lines? If so they can take a while to process depending on the school. Mine took about 3 weeks.

If you already purchased and requested to send it to the LSAC then you might wanna call the office at your school to see whats up as I'd imagine it should not really take more than 3 weeks.

Yes, grind those PTs at this point. My biggest leaps in score was by grinding PTs. Depends on how you score on your LGs on whether you should finish that section or not. If you're not doing so hot, finish LG too. To be honest at this point, you won't really be able to make any radical change in your reading comp because that section is by far the least learnable. Maybe take a look at the section focusing on how to tackle RC questions, but outside of that with a time crunch its better to move on to PT. Focus on maximizing your LR and LG. I was in the same boat as you, barely even looked at RC curriculum but I was able to score nearly a 170 on the June Flex just by maximizing LG and LR (on PTs I got about -2 on each). Not optimal, but it works I guess. I'd still recommend blind reviewing RC as well as looking at explanation vids for RC from your PTs though , could give you a little bit of an edge.

As for the LSAT flex, I scored right near where I was on my PTs, so I think you shouldn't have to worry too much. The system is pretty efficient and usable, I'd imagine you'd probably score near your PTs as well.

There could be many reasons why you're missing them, but I know for me the most dramatic change I saw was by truly understanding what each question stem is asking. If you don't have time to finish the curriculum, I'd suggest making notes on the steps to tackle each type of LR question, and then try memorizing them so that when you see a question stem, you immediately now what steps you need to take. Then try applying them on each question you face in a LR section. This tip alone probably gave me an extra +5. No guarantee it would work for you since I don't know exactly why you're missing questions, but it most certainly would not hurt and does not take too much time.

First off, in terms of games you look over per day, it really depends. I could be reviewing and redrilling 10 games per day, but if I'm not learning anything its useless. Don't focus on how many you're foolproofing a day, make sure you really understanding the games (quality>quantity). You want to understand them so well you could explain it to someone who has never tried the LSAT before. Also in terms of which games to foolproof, you can afford to skip some. The key is you need to know which ones to skip. When I was in a time crunch, I skipped games that I had reasonable certainty that I messed it up because I wasn't focusing on it or I made on tiny silly mistake, but made sure not to skip the ones where I messed it up because I truly did not understand it. This is because me getting it wrong had less to do with my understanding of LG so fool proofing wasn't as worth it. This is not ideal, but it could get the job done if you do it correctly. This is what I did and I've gotten -1 on LG a few times, so it worked for me. Also, keep in mind since you're aiming for a 160, you can really afford to miss a few on LG. Don't bash your head in trying to perfect LG as for some people (like me), I was able to improve quicker grinding LR so you might be able to reach that 160 a lot more efficiently. Studying smart is just as important as studying hard. I'd say you only need to worry about perfecting LG if you want a HYS or T14 type of score.

If money is not an issue, definitely try again. Like someone else said, 173 is a great score (congrats btw, just got a 169 on the most recent wish I got ur score lol), but its always better for you to be way above the median so theres almost no excuse for them rejecting you.
