Even if you registered as a customer in the Hazmat University store, if you haven't registered as a student in the Hazmat University Online Learning Center, you will need to do so. You can use any valid e-mail address and password, including those that you may have used as a customer in the store. Keep in mind that the information you provide in the Online Learning Center is kept separately from your customer information. If you change any of your Customer information in the Store, including e-mail address or password, it does not update your Student Record in the Online Learning Center. The same is true for any updates you make to your Student Record in the Online Learning Center; such updates will not be applied to your Customer Information in the Store.
