im assuming you did this untimed test and rechecked your answers on every section. if that is the case, here are my incredibly humble suggestions:
- first test: take this test and dont time it. but, once you find an answer, dont go back to it. only go back to those questions that youve skipped. then figure out how much time you spent, as well as your score. if you still score 180, then go on to the next test. if you score below a 170, do another test the same way after going over your strategies again. a bulk of time spent on double checking answers means that youre unsure the first time around. this will kill your time. you need to be more confident of your answers on the first try.
- second test: take the amount of time that you took on the first test and divide it by 4 (im assuming youre not doing an experimental section in your prep. if you are, divide it by 5). this is the amount of time that you should use per section for this test. take the test with this amount. once you do that, if you dont score 180, then you need to relax. this might indicate that you work terribly under time constraints, no matter what the time might be. learn to relax and pace yourself.
- third+ tests: once you master the second test, take 15 minute increments off the section time until you get to around 45 minutes per section. once you get to 45, take off 3 minutes at a time and keep seeing how you do. if you are getting consistent scores, youve beaten the time thing and you just need to do it a bit faster. if you are getting worse and worse, you needt o relax more now. if the time thing is killing you, the only way to get over it is to keep taking practice tests.
these are just my suggestions...some of it worked for me...my first untimed test didnt take me 2 hours a section, but the strategies implemented were pretty similar.
