Whoa that is high!!!
I will just go straight to the point here. I am just finishing up school and I will have to honestly say, If I had to work 1 hour a week, I wouldn't have been able to do it.
We started off with 65 in our class. We are now down to 40. Those of us that are no longer here, it was either because they couldn't pass the Math or they couldn't make it, because they were having to work and not able to study. These instructors pull rabbits out of their hats and ask you to do a huge project and bring it back the next day. There were many of us That would get together and go, OK, you do 1-10, I will do 11-20, you do 21-30, and then we would meet back together early the next day, to get one anothers answers. It is called team cheating/learning, but there was no way, we could have done it, because aside from that class we had 4-5 others we were trying to read for, or study or recopy notes, etc.
is tough and quite frankly if you feel like you are not going to be able to make it, maybe you should step down and give that person that is on the alternate list the opportunity.
Plan on spending anywhere between 20 and 30 hours a week on learning outside of class. If its a very tough year but it is VERY much doable.
