We strongly advise you to not work in more than one course at a time or have multiple courses open in separate browser windows. Progressing in more than one course or keeping more than one course open at a time is considered fraudulent in some states and doing so puts you at the risk of penalties or license suspension should your state discover the behavior through a periodic system audit or other means.
In addition, having more than one course open in your browser window, or multiple browser windows causes technical errors and could cause a delay in your course completion.
