Financial HEIRs uses a British model of teaching popularized by Oxford and Cambridge, where you can interact with the professor whenever you prefer.  Adults are presented a small amount of content, typically a 15-minute online video class.  Next you will try to implement a change.  At any point during the process, if you would like to interact with the professor, just schedule a question/answer tutorial.  Keep in mind that you can just watch the video and implement the simple principles if you find that more efficient.
