Welcome to the Chemistry 141 Homepage. This page contains all information pertinent to all sections of Dr. Haefner's CHEM 141 Fall 2017 Course

 

Additional Practice problems have been posted (scroll down to Exam Spots) for:

Worksheets! Worksheets! Worksheets!

****** CHEM 141 Grade Calculator ****** COMING SOON

I have set up an excel spreadsheet that will calculate your estimated graded based on your current scores and estimated exam and lab scores. Download the file, input problem set scores, exam scores, and estimated lab score out of 200 pts. The spreadsheet will give you an estimate of your grade.

Please report any bad links to me.

Reminder:
In order to do well, you should be doing as many problems as possible. This includes the practice problems.

Simply working spots will generally not be enough to earn the best grade. Attempt practice problems without refering to notes or the exam. If after 10-15 minutes, refer to key or notes. Make note of where you were getting stuck and work on reinforcing that concept.

If you are having difficulty working the problems or understanding the material, NOW is the time to come in for help. Don't put it off. You will not be able to cram for the upcoming exams in one evening. Also the material/concepts that we are covering will be used throughout the semester. You must understand them to understand the remaining material. Please take advantage of my open door policy and come in for help or clarification.

I have an "open door" policy when it comes to office hours and typically if I am in my office I will be available for questions and extra help. My schedule can be found by clicking here. Please take advantage of this opportunity!

Also feel free to e-mail me (shaefner@bridgew.edu) with quick questions or concerns. I will try to reply respond as promptly as I can. .
