We didn't have a math test the first week. Our math exam was about the 6th week into the semester. You must get an 80% on it to stay in the program-you get 2-3 tries I believe. But trust me, you want to pass on the first try because there is so much going on that you don't want to have to go back and take it again while trying to study the current stuff to keep up.
They don't really go in order of units. Monday-Wednesday are lab days and Thursday is theory.
The first week in lab we did hand washing and mobility. And then going over syllabus etc. our first skill check off (hand washing) was on the wednesday of the first week. That day was also when they introduced our first major project of the semester for lab.
Our first theory class of the semester on the Thursday was just going over the student handbook and syllabus in great boring detail. And they introduced the first theory paper, the Well Elder Project.
sorry if that's too much detail, I had the calendar in front of me so I just went through each day. Also I suppose it will depend on who your teacher is as to how the semester goes. We found out that each teacher was really different. I had Neuzil.
anyway, happy to answer questions for whoever has them. I wish I had someone to give me details and lessen my anxiety before the semester started!
