Firstly, if you paid with a credit card, dispute the charges with your CC company immediately if you want to get your money back. Have the proof of the item's description etc., screenshot will do.
I was in a similar situation, bought what i thought was a physics book (if I read the details more carefully I would have seen that it said it was just an access code) but in the description it read "mint condition, no markings on pages, no pages missing." What I got in the mail was an envelope with an online access code. Paid $60 for it. Disputed with my cc company, and just based on that misleading description he wrote the money was credited back to my account within a few weeks, didn't have to send the product back or nothing.
But this probably isn't your main concern. I don't know how bad it is so what I'm gonna suggest could be a huge waste of time or it could help you out.
-Circled answers=> Circle all of the other answers the same way the first one was circled
-Highlights=> Maybe you could highlight other text around it to make it more uniform. Same with underlines. Underline it all, and try to ignore it while reading the passage.
-Writing=> Cross that **** out, don't pay attention to it. Shouldn't be a major issue
