My advice for thesis writing (if it's your first time writing a major paper) is to simply write. Then revise, revise, revise. Everyone's first draft is crap. Fact.
Best of luck to you!
It certainly won't look good if you accept, show up, and say "Actually, I wanted to be in Program X."
But how you handle the matter is entirey up to you. I'd think you'd weigh things like, whether you want to be at that Uni, whether you have other/better offers, whether you feel changing would create problems, etc.
I would also assume the program that you wanted is already full.
The GRE is often the crux of this matter. May I say:
the only thing worse than "My GRE scores are V145 & Q147. What are my chances at Stanford?"
is "I got V170 & Q168. Should I retake??"
First, I believe the classroom is a political space.
However, dissenting from a lead professor (or the field/academia in general) can put you in dangerous waters.
Tread carefully.
It truly depends on the demands of the course (i.e. grading load), your abilities in planning (or wingning it), and how dedicated you are to coursework or professional development (pubs, conferences, etc).
Of course not. But I feel that the landscape is changing and this is becoming increasingly more common.
I applied with multiple publications: a book chapter, articles, reviews, a professional blog.
Yet, I agree completely that publishing junk for the sake of publishing could backfire.
Many departments in literary fields are encouraging their students to graduate with at least one publication, so you have plenty of time before it's a concern.
I think two is a good number, even for programs that ask for one. Yet, they should be notably different. For example, one on syntax and another on phonology.
However, if MIT allows three writing samples then I would strongly consider submitting three, but only if they are all strong.
Absolutely!! But only if they are all strong!
I would also recommend additional letters that speak to your varying strenghts. You don't want letters that all say the same thing.
I suggest 3 letters from profs you've had at least one course with and can speak to your academic abilities. AT LEAST 2 of these NEED to be in your proposed field.
The other two should speak to some other aspect. Ask them to emphasize research or teaching that they are familiar with. Perhaps a strong professional letter.
As long as they are solid letters. Many people have a hard time finding 3 LORs, let alone 3 strong ones. Just the fact that you acquired 5 strong letters will speak volumes.
