The advantages of the classroom based LPN school is personal contact with your tutors and other students who can provide strong support networks to make  sure that you do not fall behind to far should you find some of the study challenging.

The advantage of the online LPN school is flexibility and adaptability.  You can study at your own pace, and you are likely to get one to one tuition, albeit in an online environment.  Which one you choose will be entirely down to whichever you think will suit you best.
