Exam 1
Some changes in the schedule:
Thursday, January 19, 2012
Help Center
The Help Center hours have now been established for the PH10X courses. The schedule (including room) is found here (also linked on the class web site):

Friday Quiz
Just a reminder that there will be a ~10 min quiz tomorrow (Friday, Jan. 20). The question will be similar to one of the Quest homework questions. You are not allowed a formula sheet for the weekly quizzes (but you can have one for the hour exams). So, you will need to remember the basic equations for 1-D motion, including constant acceleration (with gravity as an example). I'll take 30 min or so at the beginning of class to discuss the homework, then give the quiz.
Email me or stop by my office if you have questions.

Using Quest
Some comments about using Quest:
- You get unlimited attempts at answering problems. However, the credit you get for answering it correctly diminishes the more attempts you make.
- You can get negative points for multiple choice questions if you have too many misses.
- Use the correct notation when entering powers of ten. For example, Avagadro's number would be entered as 6.02e23. I don't think that 6.02x10^23 will work.
- Be careful about precision. Quest states that an answer within 1% will work, so an answer with 3 digits should suffice. However, if you have an answer that involves several factors and you round off one or more of the factors too much, then your final answer will not be sufficiently precise even if you give it with 3 or more digits.
- The accuracy of your answer also depends on the accuracy of the constant(s) you may have to use in the problem. If not given in the problem, then there is a list of constants in the Quest help section.
