ONLINE A&P

HI, Ii just signed up for this site because i am currently a nursing student at Keiser University, i am still taking my pre-req and i failed the TEAS 1 time. i have 2 more times to test out, how are you able to pass this program with work and etc? i am so stressed out with A&P 1 i am almost about to quit my job, i have been pushing ,myself so far but i know it will be a time where i have to give all of my focus to learning, i am afraid that i will not pass these pre-reqs and have to get in more debt and redo this program, my problem is that i am unable to focus, since i am taking this class online, i literally just read enough to be able to pass the test and weekly exams,. i think that if i was on campus it will benefit me because any questions or clarity that i need i am able to obtain right on the spot. Does anyone have any ideas or suggestions that will help me? my current schedule is monday -friday work @ 10:30am -7pm. then i work out from 8-9 and after that i am beyond drained. since i started this class, i cut out the working out and i try to replace that with reading, but its literally 25 pages per day, and then i take a quiz 1 time a week and 3 labs.
