End of the Year/Deadline for Late work/Extra Credit is Monday 6/10!

Can you believe it is already the end of the year!?  This week we will be taking the Final Exam.  It will cover our units on Rotational Motion (7+8), Waves and Sound (12+13), Light (14+15), and some Electrics.  I highly recommend that you do the practice problems to help get ready.  Some details about the final:

1) On Thurs 6/13 at 10:30-12:30 for 5th period and Fri 6/14 8:10-10:10 for 3rd period
2) A combination of Multiple Choice, Problems (show work, include units, and sig figs), and short answers
3)  You may use a 4" x 6" (or smaller) note card written on both sides.  Go through the review packet to help determine what you need to know.
4)  You must finish in the time allotted unless you have an IEP/504 plan that gives you extended time
5)  Cheating will result in a 0 for the final exam (not partial credit).  Don't do it!
6)  Exam will count as 20% of the semester grade
