Also, yesterday was my first time doing LSATs in 4 days because I have a 3 midterms.
well that's why you can't concentrate. even though you stepped away from the LSAT for a few days you've been studying for three midterms! studying for midterms alone will burn a person out, i can't even imagine studying for midterms and the lsat at the same time.
i think it's reasonable to take a practice test before your break, but after that it might be in your best interest go off and enjoy your spring break without studying. relax a bit and you'll come back with a clear mind and ready to study some more. you might be rusty for a day or two, but it's february and the test is in june. you have plenty of time
