Macomb Nursing (MCC) instructor for 1510

Hi, I just started the nursing program this week and i have a question about the instructor for 1510. I have try to research on her/him as to what kind of teacher is he/she but with hardly any luck. I wish to ask anyone that has had him/her in the past what kind of teacher is he/she? I see there is only 3 exam and no other points form HW or project etc. The fact that our grade is based on only 3 exams, scares me to death. What if i fail the first exam? I will be probably failing the the entire program. So let me know if you guys had him/her and how should I go forward with the class and the exam? and how should i study for the exam? do his/her notes help? or do i need to read the book? I don't like to read the book and like the notes as they seem to help me, but don't want to wait till the first exam to find out the are not enough.

Thanks in advance.
