Thank You for requesting for feedback, following is my feedback,
1. Expectations not set - In terms on how many E-mails will I receive , what is the duration , when is the last e-mail gonna come. No expectations set at all.
2. No particular order in receiving E-mails , I believe there has to be a sequence of education.
3. A final e-mail with a attachement document consolidating all the formula and explanations.
On the flip side ,
The explanations are simple in language clear and consise and to the point , which is easy to understand and remember.
