Email abraskin@mbusd.org with a formal letter addressed to an unknown student that will be taking AP Computer Science next year.
Introduce yourself with a brief background of what you knew before you took this class, why you took it (be honest!), and what you expected it to be like (again, please be honest).
Then, tell this student what they need to do to be successful in this class.
Finally, you may choose to include your name or simply sign it an anonymous (but school appropriate) tag line.
