Grade Estimator updated - take a look!

I've modified the Grade Estimator (it's in Course Docs) in 2 ways:

1. It now shows both your estimated numerical grade AND your corresponding letter grade, and
2. It now has an area to check your estimated grade out if you are taking me up on the Assignment 2 offer.

I strongly recommend taking a look at this spreadsheet, especially if:

1. you absolutely need to get a certain grade in this course, and are confused whether it's realistic that you'll hit this mark, or
2. you have had a rough time early on in the course, and need some help deciding whether it's best to drop the course or not
