General Chemistry, Sections 1 and 2
(A syllabus from Spring 1998 that is being reworked into the 1999 version)
Background exam is given the second hour of the class. In my experience the foremost problem in the course is ability to handle comfortably arithmetics, algebra and word problems. Those who have difficulties passing the background test are very likely to struggle during the course. My advice is to drop CHEM 210 right away and take mathematics instead. CHEM 110, in general, will not remedy this problem.
A sample of an old background test:

30 Pre-final review
May 6 Final test, 10:00 - 11:50
Recommended materials: A calculator with scientific notation, logarithms, goniometric and statistical functions (You probably have one already. Just check that you know how to use your own calculator. Each has its own idiosyncrasies that you have to master. Do not borrow somebody else's calculator immediately before a test unless you know how to operate it. Needless errors and lot of frustration is created if a calculator "deceives" you.).
Programmable calculators are acceptable during tests as long as they do not contain in any of their storage devices the course material subject to the testing. You cannot share a calculator during a test. Computers (laptops, notebooks, etc.) cannot be used during tests.
Have a calculator and a pad for calculations ready for each class period. The lecture will be always interspersed with your active participation.
For tests and quizzes it is assumed that everybody has a calculator, pencil No. 2 (for computer grading forms, if such are used), a pen (only answers written in permanent ink can be reconsidered if you suspect an error in grading of an essay question or expect reconsideration for partial credit), and substantial knowledge to answer correctly the questions.
Helpful for those insecure in mathematics are the following books: Miller, Lial, Schneider; Fundamentals of college algebra (MATH 110 book); Dorothy M. Goldish: Beginning mathematics for beginning chemistry, 4th Ed., Macmillan, New York, 1990.
EXAMS AND GRADING:
Hour tests (3) 50% (300 points)
Comprehensive final test 33% (200 points)
Laboratory 17% (100 points)
TOTAL (600 points)
There will be 11 quizzes, each worth 10 points. The sum of the quiz grades (up to 110 points) will substitute for the hour test with the lowest score, if the quiz sum is higher. A minimum grade of 60% in the laboratory is required to pass the course. Bonus credit may be available through taking computer aided practice. Watch for a specific announcement in the class.
NOTE THAT TAKING THE FINAL TEST IS REQUIRED.
In general, cheating means presenting or using work which was not done entirely by you and, in the case of in-class examination, it includes also presenting or using your work which was written outside the classroom. You may not talk or pass notes to each other on any subject. Having other materials with you within reach during test or sharing calculators is cheating as well. Keep what you may need for the test within reach and keep what you should not have with you in your closed packs or do not bring it in.
THERE WILL BE NO MAKE-UP TESTS OR QUIZZES
Note that the rule of replacing the worst test with the quiz score is your insurance against missing a test. Similarly, since even with one missed quiz the total may add up to a happy 100 points, there is a built-in provision for missing a written work. Hence, there will be no-makeups for any reason. Do not inquire. Those who take all the tests and quizzes are not curve busters for those who miss one. All are graded on their own merit. There is not a curve in the class.
Your class percentage will be calculated as the sum of all the points earned, divided by 6. The grades will be as follows:
A Outstanding competence 90% and more
B Above satisfactory competence 80% to 89.99%
C Satisfactory level of competence 70% to 79.99%
D Marginally satisfactory competence 60% to 69.99%
F Unsatisfactory level of competence < 60% (or <60% in lab.)
