I started taking the python skills test and finished answering the first few questions; however, I had to leave the test in between for another obligation. I remember reading clearly somewhere that you could leave a skills test in the middle and continue working on it later from where you left off. However, when I tried to get back to the python skills test, it indicates that I already took the test and have to wait 90 days before I can take it again. Why am I getting this message? How come I cannot continue the test from where I left off?
