Mentoring

I didn't fully understand the idea of being stretched thin until now.
For a mentoring program we call Frientors at Cleveland High School, juniors mentor freshmen into creating a path for themselves that lead to success. However, it's much tougher than it seems, especially if you're really dedicated to tutoring and your mentees need a lot of attention.
I find myself stuck over five mentees. I'm lucky that I have 3 mentees who I have time for because they don't need too much attention; however, the other two are a different story.
I just recently got a new mentee from a recommendation from my advisor (who started the program). I actually really like him now and we're buddies. The thing about him is that he just needs to focus in class. He's actually pretty smart and knows the ropes, he's just climbing up the wrong one at times. I think I'm going to be okay with him though because I gave him a little assignment to do and he completed it on time. I think for him it'll be fine, but my last mentee is the one making me the most worries.
His grades are not where they should be and he's only at school every other day. Coincidentally, he's not at school on the days when I plan to meet with him, and he knows when I meet with him. I think and hope it's just a coincidence however. For this last mentee, I think there's a problem at home for him. He can do his work and pays attention well when you talk to him 1-on-1, but his attendance just destroys his grade. I can't get him to school and he tells me he's really/too late a lot of days because he can't wake up. He's told me he's gone to the doctor, set multiple alarms, and had his parents wake up to no avail. I feel now that there's more to it. I think I'm sending this info to the people with the paychecks, trained to do this.
We'll just see how it goes. I'm hoping for his sake that it will turn out okay in the end.
