I realised that I have capitalised the word ‘Physics’ once in my essay. Its not capitalised anywhere else ( just used the word 2 times )
Also, in one place, I have capitalised the word ‘Dollars’ and in another place, its written as ‘dollars’
Should I worry about these mistakes? Will they hurt my chances?
Also, I have written a sentence like " All that matters to me is giving my 100% " . Is writing ’ 100%’ instead of ‘100 percent’
okay?
I work as a copyeditor. These will not matter to your chances. The first two are just inconsistent style that really aren’t that noticeable. The third is a style choice that could go either way. None of them are noticeable actual mistakes. Don’t worry about it!
You’re one of many posters worrying about one or two very minor mistakes. I hope you have the perspective to realize none of this is like writing for a hs teacher, who might take points off for misplaced capital letters.
They’ll probably spend about 20 seconds reading your essay. It’s unlikely they would even notice.
