I think taking the time you need to understand the stimulus is key. I've found that when I use my imagination and really try to visualize a stimulus, I understand the stimulus a lot better and it allows me to see the structure of the argument easier.

I wouldn't worry about a 6th try coming off as desperate. I'd say it shows you're determined. Also wouldn't worry about waiting, but only if you think you can get a better score. If you haven't already, you should look into how some of the high scorers improved. Check out the 7sage podcast. Full of interviews where ppl went from 150s - 170s. I had also underestimated this test. From what I've read you have to blind review and when you're reviewing you should write down why you did or did not get X answer correct. This allows you to see your reasoning so you can correct your mistake on other similar problems. Also check out the loophole for logical reasoning by Ellen Cassidy and the LSAT trainer by Mike Kim. Heard good things about them. Im sure if you change up your study habits, look into some other methods like those books above and keep practicing on 7sage you'll see an increase. Good luck.

Highly recommend as a supplement to 7sage. It has helped change my thinking and also has given me a lot more confidence when answering questions.
