Terrible at night. Kept kicking me out of teaching modules(10 of them) AFTER I paid up front for the course, and after luckily refreshing back into the course, did NOT give me the option of taking the test, which is why the course was taken. It only offered me to go to the beginning ( which would start the WHOLE PROCESS OVER again, or ho to the end, which them kicked me out, and I was NOT ALLOWED back in,UNLESS I gave another $50 to take over. Now as for the contentb- EXCELLENT TEACHING. I learned SO MUCH, as I took my time over a 4 hr. period. Thank God, your daytime staff was able to set up the test on my cell phone the next day, WHEN the office hrs started, but I start very early, and was NOT ALLOWED to operate the scissor lift at work, UNTIL the safety coordinator at the job sight was able to download a copy of the completed-successful test (80%+) It was VERY FRUSTRATING to lise 4 hrs of sleep time for nothing, and still have to go to work, exhausted, with no access to the machine. I would have preferred my rest, then I could have taken the test at my union hall, which was only 15 minutes away. Thank u, to whoever helped me the following morning
