I asked them to give themselves advice on how to succeed in this course . Things they know now which they wish they had known then . And they gave me some pretty awesome reflective letters , full of advice useful to my classes this year . Instead of me telling them that doing their homework nightly is important , or that cramming at the last minute doesn't work , they now have it from the horses mouths . 
Question: What may have been their reason for writing reflective letters ?
I assigned them to do it .
