Transcript Major Review for Exam 2 – Spring 10

Welcome
• Please sign in at the front..
• Please be aware that you will be put into a
team: 1, 2, 3, or 4, so please go ahead and
break yourselves up into these teams so that
we can get started quickly. If anyone comes
in late, please take them into your teams.
Don’t just leave them hanging.
Getting started
• This review will be posted on my SI resources site
(See Vista), so there’s no need to write everything
down. (unless you just want to)
• This session is much different than a regular SI
session: this is a fast-paced review rather than
going into the material
Rules
• Each team will have a chance to work together to
answer questions in order: Team 1, 2, 3, 4
• If the team cannot answer all parts of a question, the
question will be passed to the next team (this is
separate from the bonuses).
• Please put your notes away unless you are writing in
them, no points will be awarded for finding info in your
notes.
