Is the Optional Supplement really optional?

Williams lists their supplement about tutorials as optional. Do applicants who do not complete this supplement have a chance of admission, or is this a requirement in disguise?

Thanks for the help.

Yes, it’s really optional. Kids get in every year without completing it. That said, it’s an opportunity to add something to your app, and if I were applying I wouldn’t want to squander that opportunity.

bumpitty bump!

Any other opinions/thoughts?

Totally agree with @marvin100, it’s absolutely possible to get in without the supplement, but if you’re borderline it will almost certainly be the thing that would get you accepted over another student.
