Well they did send me a paper with sample problems that I could practice on. It looks like the placement tests are based on Geometry and Algebra 2. And calculators are not allowed during the test!
I'm not sure whether or not the orientation has passed yet.
A friend of mine didnt recieve any notification from them either. She called one day and was told (by an administrator that said she was too busy for details) that she had gotten in (even though they didnt send any notification). She recieved her welcome package about a month later.
Thanks for the congrats
