Self-study
When starting a drill you are always required to pre-select how many questions to drill. Is there a way to set it to indefinitely drill, so that you can keep going or stop as you please without having to either start a new drill over or ending the current drill unfinished? Thanks!
you might be burning yourself out! try to relax and not stress too much. 4 full length tests within a week and a bit is quite a lot, so you might want to slow down and make sure that you review your wrong answers after each test. see what you got wrong (and why you got it wrong, what made you choose the wrong answer over the right one, etc) and focus on accuracy rather than grinding out full tests so often.
