Additional Help
TAs:
TAs for the CHEM 2AL are also the TAs for CHEM 1B. You are welcome to go to any of the TAs office hours even if you are not taking CHEM 2AL. See the course website for exact office hour times, locations, and TA email addresses.
CLAS:
Organized tutor groups and drop-in sessions. The organized tutor groups
meet twice weekly for 1 hour. For more information go to their website: clas.sa.ucsb.edu. I would highly recommend signing up for a CLAS tutor group. I have heard lots of positive feedback from students about CLAS.
DSP
If you need disability-related accommodations in this class or have any questions please contact the DSP office: dsp.sa.ucsb.edu. If they cannot help you or you have any other questions feel free to email me.

Homework
- Online homework will be assigned through ALEKS (aleks.com). Your ALEKS course code for this class is PXJKP-LRFAE.
- INSTRUCTIONS: IF YOU HAVE AN ALEKS ACCOUNT
- Open a web browser
- Go to aleks.com
- Sign into your account
- Click on "Add/Change Classes"
- In the box provided, enter the course code: PXJKP-LRFAE
- Select "Use remaining time from …"
- You should not need to purchase an account because you should have purchased a year subscription when you started Chem 1A.
- Please verify that your perm number is correct in ALEKS. To do this, log into your account. Click on the ≡ icon (3 bars) in the upper left corner of the screen. This will bring up a menu in which you can choose "manage my classes." Click the down arrow next to your name and select "account settings." Click "edit" next to your school and check and change your perm number, if needed.
- INSTRUCTIONS: IF YOU DO NOT HAVE AN ALEKS ACCOUNT
- Open a web browser
- Go to aleks.com
- Click on "SIGN UP NOW"
- In the box provided, enter the course code: PXJKP-LRFAE
- Purchase an account. You will use this account for CHEM 1C as well.
- When you put in your personal information there will be a box that says "optional" enter your student ID; you MUST enter your perm number (enter seven numbers, do NOT include any dashes or spaces). If your perm number is not entered or wrong you will not get credit for the assignments.
- If you need to edit your account (for instance, to fix your perm number) you can do this by logging into your account. Click on the ≡ icon (3 bars) in the upper left corner of the screen. This will bring up a menu in which you can choose "manage my classes." Click the down arrow next to your name and select "account settings." Click "edit" next to your school. You will then be able to enter your correct perm number.
- If this is your first time using ALEKS you should look at the ALEKS instructions posted at: people.chem.ucsb.edu/feldwinn/darby/ALEKS.htm.
- Due dates for ALEKS will be announced in class and sent to your UCSB email. ALEKS assignments are due at 10 pm on the due date.
- Your lowest ALEKS score will be dropped.
- If you do better on the final then on your total ALEKS score, your percent on the final can replace all of your homework scores.
- Problems out of the book will also be assigned for each chapter. Although these problems will not be collected, they are REQUIRED homework for the class. I have seen a direct correlation between the number of book problems that students do and their overall grade in the class. Do not expect to get an A or B in the class without doing the book problems.
iClickers

- Each question is worth 0.3 points.
- 0.15 points will be awarded for trying the question.
- 0.15 points will be awarded for each correct answer.

- There are no excuses for missed iClicker points.
- More than 12 iClicker points will be available during the quarter.
