Guys, are you all doing a different test than me? im in connexus, and mine is 24 questions long. so either you are all trolling, or im just dumb.
we all have a different test
mines 26 questions wtf
Al5X1 Doesn't have all the right answer I got a 12/24 half of those answers are wrong
i have 7 questions uhhhh
none of this helped i got a 33

Bruh most of the tests are a lil bit different so you have to type out the question and answer to actually get the right answer for other ppl
wtf i have 23 answers
i'll take the bullet and use AI5X1 answers (pray for me)

1B? are you guys literally cheating/checking your answers in 1st grade?-
@nerdy kid
algebra 1b is 9th grade work LOL??
