Because of poor attendance, we have decided to change the way that Academic hours works. We will no longer have a set time where academic hours occur, instead we will be offering academic assistance based on need. If you need help with an assignment or class please email me (Colin) at email@example.com. Please give me several days advanced notice. I will get in touch with our great network of folks who have volunteered to lend their expertise to this program, and I will find someone suited to assisting you.
What I need in your email: The subject you need assistance with. The days and times that work for you.
Thanks and I really hope you choose to take advantage of this great opportunity for help.
