I took a Nurse Refresher course in Stafford, Texas I do not think the course would prepare you for the NCLEX. It was great but, really focused on preparing you for a return to safe clinical practice. No test or quiz emphasis except for enough Math and Pharmacology to ensure you could pass a work quiz. One of the instructors called it brushing off the cobwebs. I would suggest you do a NCLEX review where they will look at your previous exams and what areas you are deficient. There are several local ones that are in person. I think if you google nurse refresher program Houston you should find it. I think I cannot write a link according to the rules. I do not know Dr. Umeh Johnson but, several LVNs at my job have used her and passed.
