SUMMER WORK
FOR RISING
ADVANCED ALGEBRA AND GEOMETRY
STUDENTS
Barrie Prep 2016
● Solve part I in June, part II in July, part III in August. The idea of the review is to do little work (each of these 3 packets should take about 3 – 4 hours of work), but spread in time so it refreshes your memory every now and then and keeps alive the knowledge you acquired during the year. Of course, you can do everything in August, but by then your memory will be stale beyond the rejuvenating power of this packet. Or you can do it all now, but by late August, when classes begin, you will have trouble to retrieve this knowledge from the dungeons of your memory. If you want to invest your time poorly, go ahead.
● If you solved a problem and the solution can be checked using your calculator, by all means do it. Moreover, consider the checking-‐with-‐your-‐calculator thing part of the problem.
● Work hard at resolving discrepancies. Not so hard that it mars your vacation (intelligence includes having a sense of proportion).
● If a problem or group thereof is still driving you crazy, you will find help at [email protected].
USE IT! Be explicit about what you did, what you got, and/or what you find puzzling. A couple of sentences. You may include a scan in your email. Help may delay a day or two.

● Turn in the packet with your solutions the first day of classes. It will be a conversation piece the first week of class.
● Starred questions deal with material not covered by all the students
● Enjoy your vacation!
