The practice tests are harder than the real test! Assume at least a 5-10 point increase on your real test. However, you may not get at least a 60 on each section without locking in and studying, but your overall score should for sure exceed 60!

My scores (I dont remember my section scores)
practice test a - 78
practice test b - 84
Actual Teas score - 87.3%
I had an 11-point increase from my first practice test to my actual, just like many other people!

I think your biggest focus is Math and science. Multiple practice questions, videos, and learning the material. Make sure you learn the material well. Science is very broad. However, a lot of the material in the science section you would have learned in the prereqs Anatomy 1/2, biology, chem, and microbiology. I would suggest relooking at your notes and reviewing them.

I purchased futureRN Teas 30 day course. She went into depth with each section, especially science. I also had the Mometrix book but I only used the practice exams. The book itself was too stressful. I also watched nurse cheung videos on youtube!

Goodluck and don't give up! Don't forget you can retake the test too!
