Glad it worked out for you. I've found the "W" policy is different for each school. In my area, most of the schools
allow no more than 2 W's in Anatomy, Physio and Micro.
You still have to be careful, since a lot of nursing schools have adopted GPA preferences. Even if 2 W's are allowed, if it brings down your GPA, that can also affect your chances.
Schools also change these policies all the time, so it's good check back now and then, just to make sure they haven't changed any criteria while you're going through pre-reqs.
I've known students who were wasting their time, still taking courses after they got 2 W's, because they didn't check criteria changes. Others got caught in a GPA preference change, which was implemented after they had finished most of their pre-reqs. It delayed their chances of acceptance by a year or more.
So it definitely can be tricky business. Unfortunately, the schools don't always do a good job of telling everyone what's going on. Most of the time, you have to contact them to find out.
