The reason people may say this is because a Nurse Practitioner will typically require a Master's Degree level of education. Many community colleges offer an ASN (associates) and you can work as an RN once you complete the program and pass your boards. If you choose to continue your education to become a Nurse Practitioner, you will need to complete a BSN to be able to progress into the advanced studies of Nursing.
Once you have your ASN and begin working as a RN, you should be able to either 1) transfer your ASN to a local university and continue working toward a BSN or 2) pursue your BSN through an online university program. Either way, community college is a wonderful place to begin a career in nursing.
I say all this with having completed anything so far. I am in a situation similar to your own and have been researching my options and I have decided to pursue an ASN through my local community college and then go from there.
Please don't ever think yourself a failure because of which college you attend. If you have issues with testing, check with your college. Many colleges have "student success" programs that are free and can certainly help with test anxiety. I wish you the best in whatever you decide!
