How far away are from actually taking the exam? 1. If it is some time off, you may not have all the material you need to to take even the practice tests anyway. 2. If it is close to the time you should be taking it, you still need to focus on your current materials and will also need to get a hold of the study materials that are tools to help to take the test, the study guides for it BUT only closer to the time that you're going to take it, several months ahead of it.

I would think the low grade on the practice test is also because you aren't completely focused right now; you are distracted by all that it is going on with school, life choices, and stressed about it all. I can't say that even that practice score is accurate given the circumstances. Take a deep breath and a step back from it all.

Work on your current material, and wait to work on practice tests during the break AFTER you get the study guides for the tests to go through first. Knowledge before testing is setting yourself up for failure and that isn't reality. You CAN do this but in a different order and with great success. Focus on one moment at a time, and the task at hand, you will get there but you have to take the steps to get there; taking flight without your wings will only send you crashing back. You will get there and with flying colors, you really will.
