Dear ,

 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.

Thank You
Irfan
