It depends on the person answering but mostly, yes!
Not a single person - there are many thousands of people contributing to the site.
Yes it is.
Maybe you're asking the wrong questions.
Most are but it depends on who answers them. Anyone can answer a question and some are incorrect.
Because people are rude
no! you can find, maybe two out of five correct answers.
Because it gives you answers that are correct!
im angery no 1 is giving the correct answers. trolled!
You will both get into trouble if found out ! Tell the teacher that he is giving answers out. I wouldn't trust his answers are the correct ones anyway.
You can get 60 questions wrong, which leaves you with 140 answers correct, giving you 70%.
This site gets their answers from the general public, meaning, random people. Amongst these people are some who are not as smart as you may like therefore giving answers you may see as dumb.
This site doesn't do homework for you, or give answers to test or exercise papers. (We don't even have access to them.) And personally, giving out the answers on a website is so sleazy that I wouldn't trust the answers I got from a site that would do that.
