A close friend has asked me this question several times. She wants to know about some reliable online university courses for substitute teacher qualification , medical billing or psychology. She found this website called “Universal Class” online that has a fee of 20. 00 dollars, but she’s wondering if it’s reliable or not. What are some online university courses that I can recommend to her?

That depends what the qualifications are in you state.
In Missouri all you need is 60 hours of any college classes and to pass an FBI background check. I would check with your state or district to see if they require any specific classes. Most are so desperate for subs, they do not.
