On weekends I am seeing my maths tutor on Sunday at 2PM, so around 8AM for you, probably not an issue. other than that I am free most of the time at weekends.
note that Sunday suits me better, as I am often visiting people on Saturday evening
Most evenings I should be free, both week days and weekends. basically 7 until 11, though I might be able to push for 6:30 until 11 if my parents are supportive (they probably will be!) that is from 2 until 6 in Ohio I believe.
can't do Fridays ever, as I run pathfinder pretty much from the moment I get home from school and I only start packing up at 10.
honestly If its a set day every week, I should be able to be on as long as its not running later than 11PM for me, or while I am at school.
