No matter how much confidence you may have in your abilities, do not attempt to complete school work from Spring semester after you have already started your summer clerkship.
This is doubly true when you have a 30-page paper due the same week as a reply brief in federal court. Choosing between an F and malpractice is simply not a feasible option. Staying up until the wee hours of the morning when you have to work in a couple of hours, however, is an option. The only option, it appears.
