<p>I have gotten to the point where the only mistakes I make are occasional plug-in errors and sometimes running out of time for the last question, but very rarely. I also very rarely struggle with finding a method to do the last problem in a section (maybe once every 7-8 tests). Should I stop doing full math sections and just focus on making sure I understand how to do the last 2-3 problems in every test? I just feel like I'm wasting time doing these full section math tests when I always know how to do the earlier problems. I just keep making 1-2 dumb errors per test on the easy questions, but I figure I will just have to be extra concentrated on test day.</p>
<p>You should do an entire test where you are “fully concentrated.” Otherwise, your results will never be accurate. If you are making careless mistakes consistently, perhaps the problem isn’t speed. As test day gets closer, focus on your weak points. While the test is far away, I suggest full sections for practice.</p>
<p>I second what I3auer says. You need to be under the time pressure for it to be realistic. If you’re pressed for time, doing only the last 3 problems won’t really help solve your problem. (lol math pun)</p>
<p>I had the same problem and still do. For the last 8 or so practice tests I took, I scored 750+ for all of the math portions but didn’t get a single 800. I used to answer questions from the beginning to the end, but realized I wasn’t managing time well. Part of this is because I usually double-check everything as I do them, so I recently started doing the test backwards (started at No. 20 and then did No. 19, then 18, and so on and so forth. This helps me because I am more focused at the beginning for the harder problems. Also, when time is about to run out, I only have to complete the easy problems at the beginning of the section and the lack of time forces me to not double check my answers to the give-me-free-points questions.</p>
<p>Hope this helps</p>
