Exam #4 Friday May 2nd; 50 multiple choice questions
Bring a clean, uncrumped
ParSCORE Student Enrollment form
(the larger 6"x11" pink form, same as for the other 3 exams), some
#2 pencils & an eraser.
** To save time, fill out your ParSCORE form before the exam starts. Be
sure to put your Red ID on both sides of the form, and don't add
an extra zero to the front of your Red ID number. Fill in "Test Form A"
and "Exam # 004". (Don't enter your phone number or a test code on the
front of the form.)
Please follow the instructions for filling out the
scantron forms - don't throw away points!!
Common errors include:
. putting an extra zero in front of your Red ID
. incorrectly entering your Red ID
. not filling in "Test Form A"
. not filling in "Exam # 004" correctly - it is "004" not "4"
. accidentally filling in two answers
. not erasing an answer fully
Please be careful!
Calculators are allowed for this exam.
Material you will be responsible for knowing:
- All class notes: The class notes are by far the most imporant
source of information for this exam.
- Textbook: Chapter 5, 10, 11, 12, 13
- All homework problems since the last exam and all reading assignments
(including web pages and any homework that was not collected)
- Make sure you understand all the homework problems.
- Don't forget the usual definitions and concepts such as the speed of
light, temperature, wavelength, Kepler's 3rd law, star formation,
parallax, conservation of mass, conservation of energy, conservation of
angular momentum, Newton's law of gravity, spectroscopy, etc.

General hints for the exam and exam preparation:
- crumpled/folded scantron forms will get a ZERO if they jam the
scantron reader!
- Make use of the Astronomy Help Room
- Read the "Summary of Key Concepts" section at the end of each chapter
several times.
- Make use of the Astronomy Help Room
- Read the material from on-line sources (all those links off the class
web page) to help reinforce ideas and concepts
- Make use of the Astronomy Help Room
- Be sure to read the textbook before the material is covered in class.
This is an extremely benficial technique, perhaps the single most
powerful tool for learning.
- As always, nothing beats one-to-one tutoring during my office hours.
