Once you've been advised, your adviser will authorize you to register. To register for classes, log in to your myLSUA account. Click the Self Service button on the purple banner at the top of the page. Scroll down and click the yellow "Continue to Self Service" button.
Under the PowerCampus image, you'll see a few links under the "Students" text. Click "Find Courses."
You'll be brought to a screen labeled "Section Search." Use the drop down menus for "Period" and "Session" to select the semester and session you're trying to register for. (100% online students: For "Period" you will select a semester that ends in a number, for example SUMMER3 or FALL3. On-campus students: Do not register for a period that ends in a number. You should select a traditional semester, like Fall or Summer, and then a session - either full session (for semester-long courses) or 2nd or 3rd session (for seven-week classes).
The best way to find a course is to type its "Course Code" in the corresponding search bar and hit enter. Once you find your course (with the right time and place) hit add. Repeat this process for each course. You've now added your courses to your Cart. You are not in these courses yet. To complete registration, click "Cart" at the top of the page. Scroll down and click next button. Click the next button once more to finalize. The second time you click it may take a while to process, so be patient.
There are PDF instructions for advising here. Make sure to select the right PDF - either 100% online or not.
