Don't Forget To:

  2. Submit final, official transcripts
  3. Submit the Statement of Legal Residence Form (SLR)
  4. If you are a domestic student, completing a FAFSA
  5. If you are an international student, complete the Non-Immigrant Information Form (NIF)

CalCentral Tasks

Click here to sign into CalCentral. Logging in with your CalNet ID and passphrase allows you to access campus applications and services. Resources in CalCentral include: Billing and Finances, Financial Aid, Grades, and more. 

Update your contact information in your CalCentral profile, particularly your local address. Click here for resources for managing your CalNet account (changing passphrase, adding/changing recovery email address, etc.). See the information here about updating your name, if needed.  

Please review the onboarding messages and checklist items under “Tasks” on “My Dashboard” that you will need to complete. This is especially important for international students. Failing to complete tasks can lead to registration holds, which prevent enrollment, so take action early! Note that these tasks update on a regular basis, and completing one task can sometimes trigger another task to appear.

Your Berkeley Email Account

Activate your bConnected account through your CalCentral Dashboard. This will activate your email account.

  • Log into your CalCentral using your CalNet ID
  • Look up in the left hand corner under MyDashboard
  • Follow the link to bConnected to activate your UC Berkeley email address

Regularly check both your personal email that you used on your admission application and your new campus email in order to receive information from the IEOR department and the university. 

Once the fall semester begins, we'll no longer contact you via your personal email, and we ask that you use your email to contact us. 

Keep in mind that sometimes University emails can accidentally be filtered to spam.
