Seems to me like you should make this decision after Finals since this is a really stressful time.
strap a set on my friend. Its crunch-time. Nobody in their right mind likes law school right now. in fact, i'd say its a good chance everyone wants to drop out right now.
Get through your finals, see how you do and then make a decision when you are in a better frame of mind.If you have a masters in science there may be other things you might want to do...like teach or do research. Science teachers are in hot demand right now...the pay isntanywhere near what lawyers make but the hours are better and you get to do what you like.
