Hi Gabby, in order to get your BSN, you have to complete the degree program. This could take less or more than 4 years. Some of the variables involved are how many classes you take per semester or quarter, if you attend Summer Session and if any classes are required to be retaken. As long as the school you are attending offers a BSN Degree, you will not have to attend any other schools. However, please keep in mind though that upon completion of the Bachelor of Science, Nursing Degree, you will still have to pass the National Council Licensure Exam - RN (NCLEX-RN) before you can be a practicing RN. Good Luck!
