  • Current Grade Posting

    • IMPORTANT: Your final course grade will be based on an adjustment to your lowest exam score applied in the following way: your LOWEST lecture exam score will be replaced with the AVERAGE of your LOWEST lecture exam score and your FINAL EXAM percentage (assuming that the final exam percentage is better than your lowest exam score, otherwise no adjustment will be applied).

      • This adjustment can have a significant impact on your grade and serves as a "curve" that is dependent only on your performance, not that of the rest of the class.

    • The PROJECTED Adjusted Percent on the gradesheet shows what your grade would be currently if your lowest exam score were replaced with the average of your lowest exam score and the average of your lowest exam score and your 2nd highest exam score. This is only an estimate of your current standing as it would relate to the grade adjustment.

    • The PROJECTED Adjusted Percent also reflects your lowest problem set score adjusted to 6 points (max points for a PS).

    • CORRECTION: The current posting reflects a correction from the printed version shown in lecture today. Some of the scores were not transferred correctly to the master gradesheet from the Sapling spreadsheet. The current posting reflects the correct score being recorded.

    • EXPANDING YOUR HORIZONS: I currently have the EYH Go'fer points recorded. However, I do not receive a list of the presenters. If you were an EYH Presenter, please email me to let me know that you were a presenter. Please also include the title of your session.

  • Welcome to Organic Chemistry 1 Lecture!
  • Please visit the links to the left for important course information.
  • Skyline College classes start Thursday, January 22.  Our first CHEM 234 class meeting will be on Friday, January 23 at 11:10 am in 7-310.
  • The course text, Organic Chemistry, 4th ed. by Janice Gorzynski Smith, is available as a custom edition in the Skyline College Bookstore. It is bundled with the Study Guide and Solutions Manual. I highly recommend buying this set. The solutions manual is a complete solutions guide to all of the questions in the text. The reading and questions assigned from the text will be one of your key means of prepartaion for the course.
  • If you would like to begin preparing for the course, I recommend reading and working book problems from Chapters 1-2 (a review of General Chemistry topics with emphasis on their application in Organic Chemistry) and the worksheets under General Chemistry Review. The problem assignments and worksheets are on the LECTURE page. Book problems and these worksheets will not be collected, but are an essential part of your preparation for exams.
  • PLEASE NOTE: The course is not yet active on Sapling Learning, but will be soon.
    Once announced as being active, please sign up for the Sapling Learning Online Homework System:

Academic Integrity

  • Academic integrity is an important issue in all academic settings, and will be taken very seriously by the instructor of this course, and the college generally.

  • I recognize that most students conduct themselves with honesty and integrity. I also recognize that the actions of a few dishonest students and the impact of those actions on the academic process necessitate a frank and ongoing discussion of this issue.

  • Please review the Student Handbook information on Academic Integrity.
