Either she chose the wrong major, of you need new friends

That or OP needs to work on her spelling and grammar. In fact, given that the essay got a terrible mark, I'm strongly inclined to believe that her friends are correct.

Though I suppose her friends simply being assholes and the essay being graded poorly for some other reason is technically possible too, albeit just a tad far fetched.

Maybe she does need to work on all of that, but if her friend read it over she could have told the OP this instead of letting her get a bad grade.

Or the teacher chose the wrong subject to teach

Maybe op used Canadian spellings and the teacher graded for American or vice versa

Next time, double check.

Well to be fair, she did double check it. Two of her friends checked it, so her check would have been the third one.

It was your job, you should be the one who makes final check.

I did. I didn't see anything wrong.

Peer Editing is something taught very often in school so OP was in the right.

If OP turned in a paper with numerous mistakes its their fault, regardless of how many people "check" it for them...the fact that they didn't see anything wrong with it means they don't understand the language enough to notice spelling mistakes...

OP: get new friends to peer check for you, and study more....

to OP: did the teacher point out any specific spelling errors? no matter how you twist it, if you turn in an essay with mistakes and errors it's your fault (sorry), but if you truly believe you had no mistakes and you didn't get any evidence to the contrary, then something is certainly fishy.

Actually, you're supposed to have someone else check it over. You may read it over and over again, but still skip over your own mistake.

What does this even mean have you tired Spell check on a Mac on Word

Are you sure you aren't tired enough to be in here?

Sorry spell check hasn't been perfected on FML yet.

One time my mark got lowered because I used the wrong coloured pen. I know the pain

You're lucky you even got a mark!

Too true

Too true

You won't get a terrible grade just because of spelling. The whole thing must have been bad.

Not true. When I was a senior in high school, the teacher explicitly told the class that any spelling errors would result in an automatic F.

I do not forsee you as a programmer or having a focus on languages.

I've gotten several points taken off for spelling on essays when I was younger. maybe it really was a chronic issue.

I had a professor who would fail you on assignments if you had 2 or more grammar errors.

shit happens

Do your spellcheck yourself from now on on your computer, you should have done it after the first essay

I did use spellcheck. I also read over my essay before sending it to my friends, due to my last essay being ripped apart.

Sounds like your teacher has a problem, OP. Ask them to show you exactly what they take exception to. If they can't, then it's not your essay that had the problem.

get it re valued by another instructor

#40, spell check on word doesn't catch everything. It doesn't check subject verb agreement, nor does it tell you the error of switching tense within the same sentence. Either you made errors that word doesn't catch or your material is the problem.

Was that the feedback from the teacher or the excuse your friend gave you? Next time go see a Writing tutor at your school. They will help you with higher order writing skills.

No one else to blame but yourself.
