Casual reminder that the test might be different for everyone, and the teachers could know this. If you post your answers, it might end with the teachers pinpointing who you are and rooting you out as a cheater. Or at the very least, narrow it down. That being said, you can easily use a calculator. It takes effort, but there's less risk. Or you could, y'know, do the work yourself. Im not here to judge what you do. Whatever. Regardless, stay safe. If you see confusion all cluttered up like this, just go with a calculator or google. It's very easy. Oh, and change up a few answers, maybe one or two, so you don't get caught.

Just some advice.

I HAVE 23 QUESTIONS :( NOT FAIR I HAVE TO FINISH TODAYY!!!!

Beware of anyone who posts a bunch of letters and claims they are the right answers.

We have pranksters. And teachers frequently change the order of the questions and/or questions.

Thanks for the thumbs down, random person. Even though im just giving advice on how not to get caught. I think you mistake me for one of the people that go "OH YOURE CHEATING YOURE SO BAD!!!!"
