Hi There! I also got 80% on my TEAS exam. I just took it a week ago. While I was aiming for a bit of a higher score, I was pleased that I passed it. I also haven't been in high school for almost 20 years, so it took a lot of prep. Congrats everyone!
Also..... For those who are out there looking for advice on what to expect (because I spent many nights scouring this site for tips), let me give you my experience:
I studied for a solid month. I used the ATI official guide, ACE the TEAS, and the McGraw Hill 5 TEAS tests book. I also watched some of the video lessons by Mometrix on YouTube. Honestly, I found the ATI guide to not be very helpful. It IS helpful with the Reading, Grammar, and Math sections. However, a good majority of the science wasn't on my exam. I know every test is different, but I was pouring over chemistry, hydrocarbons, bonds, kinetic/potential energy and condensation/evaporation calculations and pretty much none of those were on my test. I scored an 85% in science. Not saying not to study them, but I was a little frustrated at how broad the science section turned out to be. Also, my husband bought me the practice exams. Not only were they hard for me, but NONE of the questions turned up on the real exam. My friend took the exam with me, barely skimmed the ATI guide for a week, and scored an 82%. So..... I do not feel that you NEED to buy the online exams. They are similar in layout, just not worth the price in my opinion. It is my belief that the exam is more about how you can wrap your mind around a question. I am a 4.0 gpa student, so to get an 80% was surprising. However, I have heard that many people have difficulty with the test style and that was really my problem. I totally psyched myself out. Lol. So if you are out there...... relax, breathe, study well, but don't overthink everything like I did. Read slowly and carefully. You can do it! :)
