Can I reuse old essays?

If its a similar subject, yes. I have over 30 essays saved(HS-college) that a use in every semester.

It's fine as long as you're not sending that essay as part of a writing portfolio should the college ask for one. I persoanlly was able to use a high school sample college essay that I had written, I just changed it a bit and made it shorter.

Yes. But you won't really learn anything. You are paying hundreds, maybe thousands of dollars to go to college and you don't want to learn anything new or push yourself? I suggest dropping out and going to trade school if that is the effort you are going to apply. There is less chance you'll have to write any essays.

Since you did the original, modifying it and submitting it doesn't qualify as plagiarism, taking credit for someone else's work. In other words, you would not be doing anything that you shouldn't do.

If you are writing on a topic you have already researched and written about, you certainly ought to revisit that work. Not simply repeat it, but take a critical look at what you wrote, see if you still agree with it, see how you can improve it.

well technically that's kind of sorta cheating. You did the paper yourself but not for the assingment. If you think you can get away with it than go for it.

The definition of plagiarism is taking someone's else work and portraying it as your own. Technically, it's not some else's work, so I don't think it would harm anything.

Why not it's still your work just fix it up a little to be about whatever topic you need.

sounds fine...as long as you modify it a little. it's only wrong if you didn't write it.

i guess you could. its your essay anyway.

but if it's somebody elses then its not cool as its plagiarism
