I understand the frustration with seeing the same question pop up over and over, but you guys are assuming that the issue is with the math test as already found/linked. I've run into the same problem with the English test on the first day and haven't seen a solution for that (at least going through posts so far for the new update) - in fact, the only mentions of problems with the English test (searching "english test problem") are from Jan 2020 and, from what I can tell, not answered.
Also the differences between full version and compressed aren't mentioned beyond 'you must not be looking in the right place' for the folders (which aren't THERE in the compressed version)(also not in .7 full version, just downloaded/installed it), "download the full version, scrub" or "don't run the cheat mod" (which may or my not be valid).
