“Virtually nothing in this complex has one side to it and hence, debates can be conducted on a range of matters that encompass my keenest interests.”
I didn’t add “world” after complex…
Is it going to be noticeable in a 250 word essay? Can this ruin my chances or is it insignificant?
Is it noticeable? Not really (“complex” is also a noun, so one might have to read it over to really notice it). Can it ruin your chances? No. Is it insignificant? Pretty insignificant, yes. Don’t worry; you’ll be fine!
As long as it doesn’t dent my chances, I don’t mind, I really appreciate the input. I proofread it multiple times and didn’t catch anything so hopefully its the same for the admissions team 
As long as it does not “dent” your chances? Did you write the essay? The bigger issues does not seem to me to be a minor omission of an adjective in your essay but the bigger issue pertaining to whether or not the writing in the essay reflects your command of English. I am not saying this pertains to you but your very brief post suggests it might.
US universities need to do a better job at filtering out students who don’t have a college level command of English. There won’t be two standards used to score papers and tests. US Residents should not be discriminated against in US colleges. Therefore, papers and essay tests must be graded using one standard. And that standard should be one that places considerable weight on the ability to write in standard college level English.
Too many students with poor English language skills have been admitted to public institutions. I’ve noticed a double standard among some instructors. I’d love to spearhead a movement to stop it. Students who make it to senior year without being able to produce a paper written in English at a college level should not be able to graduate. They should not have been able to get through the first year.
I don’t know if you are an international student or not but your post was telling.
I…don’t think I get your point whatsoever. Is there something wrong with the phrase, “dent my chances?”. I am very pleased with the level of command I have over the English language (its my primary language and the one I’m most comfortable with) and I’m happy with the general quality of my essays. I am an International student, yes.
I am just here to ask about the error itself so I’d like some input on that.
I think the point was that “dent” is a bit of a weird word choice (it strikes me the same way, as chances aren’t physical objects and can’t really be…dented?), but native speakers make all kinds of weird word choices just naturally, so I wouldn’t worry about it. Kinda funny to have the wrong it’s/its in a post defending fluency, though.
The mistake you’re asking about reads similarly – it kind of makes sense, but without “world,” “complex” as a noun seems like a strange word choice. Too late to worry about it now, though. I highly doubt it will ruin anything.
Is it really? I’m genuinely surprised. I thought dent obviously implies chipping away or damaging something - heard it many times, used it many times - there has never been any confusion on either end.
It is strange but I’m hoping it doesn’t attract much attention. It’s in the middle of the essay so I think it’s advantageous since it won’t leave a bad initial starting impression or a bad taste in the conclusion.
“I highly doubt it will ruin anything.” That’s all I wanted to hear, thank you 
Coming in cold, right to that quote, I tripped over that phrase trying to understand it. Then I read your question and realized what it was. I think if I was reading an entire essay and had lots of context (and tired eyes from reading so many other essays!) I wouldn’t even notice it and would automatically fill in the blank. Worse case is I’d trip over it briefly, realize what you meant and move on.
I think you’ll be fine.
As for “dent”…perhaps lostaccount would have preferred the phrasing “doesn’t make a dent in my chances”? (i.e. the use of “make” as the phrase is usually “make a dent”)
I wouldn’t call it outright wrong; it just seems like a word I would not have chosen (like what does “denting chances” do to them, y’know? How much does a “dent” cost you, numerically? I dunno). I’m guessing that’s lostaccount’s reaction to it as well. Either way, completely irrelevant and I’ll stop derailing the thread now
Good luck! The rest of the sentence sounds intriguing enough that I bet it’s a pretty good essay otherwise.
