The summer's first six weeks:
Positive -- there's an unending work supply so I can take on as much as I can handle.
Negative -- little to no feedback on written work.
A positive or negative, depending on your perspective: I've done little to no work on the investigative side. Everything is strictly research, legal analysis, and writing.
This evidently changes when you complete 50 hrs (I believe) of legal coursework. You then become eligible to go into court, at which point you'll get more involved with investigations.
