YES, but there is also a clinical component that is required and must be completed in-person. Since CNA training is so short to begin with (4-12 weeks) it is advisable to complete it all at once at a local community college. Online courses are usually expensive and you can save money by taking courses through a junior college.

Yes, you can prepare for the CNA exam online (the theoretical aspects) but you will need to attend classes at a health care facility for the clinical components that are an integral part of the training and testing.

Not possible. You have to have actual practice taking BP's, temps etc......
