Multiple All Nighters to Come: Advice Needed

Thanks man. I take 20 credits a semester to help me keep my GPA up, so if one class is going bad before the drop date, I can drop it and not drop down to 12 credits, which would put me behind for my dual major. It happened that this semester, everything is going awesome and has been very manageable until this week. I had an A or an A- in all my classes at the drop deadline so I figured why drop one? I can be a bit ahead, in case shit happens further down the road where I can only take 12 credits.
