Yes. You can log in and out of the course as many times as you wish, allowing you to take the course in increments rather than all at one time. However, the NY DMV requires that you complete the I-PIRP course within 30 days of the date you register for the course. You can complete the course in as many sessions as necessary, but you must complete the course within 30 calendar days of registration. Your data will be stored on-line for each course session. You will be assigned a user ID (your email address) and a password (which you choose) when you register for the course. You can use your ID and password to log in on any device that can access the Internet with an acceptable connection.
