Additional Help
TAs:
The TAs for CHEM 2AL are also the TAs for CHEM 1B. You are welcome to attend any TA's office hours, even if you are not currently enrolled in CHEM 2AL. Please refer to the course website for the exact office hour times, locations, and TA email addresses.
CLAS:
CLAS offers organized tutor groups and drop-in sessions. The organized tutor groups
meet twice a week for one hour each. For more information, visit their website at clas.sa.ucsb.edu. I highly recommend signing up for a CLAS tutor group; many students have shared positive feedback about their experiences.
Financial Energencies
UCSB has aid for students during financial emergencies. If you have already used up your loan eligibility, you are welcome to email FinancialCrisis@sa.ucsb.edu, and share your situation and they may be able to help you pay for ALEKS or other Chemistry related materials.
DSP
If you require disability-related accommodations for this course, please reach out to the DSP office at dsp.sa.ucsb.edu. If you have any other questions, feel free to email me directly.

NO MAKE-UP MIDTERMS OR FINAL WILL BE OFFERED UNDER ANY CIRCUMSTANCES, EXCEPT IN CASES WHERE A SCHOOL APPROVED INCOMPLETE IS WARRENTED.
If you miss a midterm for any reason (e.g. illness, sporting event, funeral, wedding), that midterm will be dropped and the final exam will be weighted at 40% of your overall class grade. Any additional missed midterms will not be replaceable.
You must take the final to pass the class.
If you take all the midterms and score higher on the final exam than your lowest midterm score, then your lowest midterm score will be dropped and the final exam will be weighted at 40% of your overall class grade.
Quiz Guidelines
- All quizzes are administered through Canvas.
- You have a 12-hour window (9:00 am and 9:00 pm) to complete each quiz. Start early enough to finish by the deadline.
- Each quiz is timed at 30 minutes.
- Quizzes include both short answer and multiple-choice questions.
- No partial credit is awarded for incorrect answers.
- Use only the exam information sheet, calculator, and scratch paper during quizzes.
- If a quiz is not completed by its due date, you can still view the questions and answers on Canvas.
- Click on the quiz.
- DO NOT ANSWER ANY QUESTIONS; simply hit submit to see the correct answers.
- Answering after the deadline results in a quiz score of -2 points.
Midterm and Final Guidelines
- The midterms and final exam will feature short answer and multiple-choice questions.
- No partial credit is awarded for incorrect answers.
- Exams are graded and returned via GradeScope: gradescope.com.
- Calculators are permitted during exams.
- An exam information page, including the periodic table, constants, unit conversions, and equations, will be provided.
- Bring your student I.D. (or another government issued I.D.) to the final exam.
- Looking at a cell phone during the exam results in an exam score of 0 that cannot be dropped.
- Sitting next to someone with the same version of the exam, incurs a penalty of 5 points.
- Headphones are NOT allowed during exams.
- Continuiing to work on your exam after time is called, incurs a penalty of 5 points.

- INSTRUCTIONS IF YOU DO NOT HAVE AN ALEKS ACCOUNT:
- Open a web browser
- Go to aleks.com
- Click on "SIGN UP NOW"
- Enter the course code: MKLNM-PQCNQ
- Purchase an ALEKS subscription.
- You will use ALEKS for CHEM 1C. You may either purchase a subscription just for this quarter or to cover you in CHEM 1C as well.
