taking two bar exams is not that bad, and it's not uncommon; i just did it (PA & NJ), along with most people i know. traveling to north jersey from philly on wednesday wasn't fun (thanks, NJ!), but then entire experience from may-july isn't exactly a vacation.
it helped that the NJ bar is not too difficult. the girl next to me in the NJ exam had just taken the Delaware exam (a three-day exam from Mon-Wed), so it could have been worse.
the PA bar subjects are:
MBE Subjects
Constitutional Law
Contracts/Sales
Criminal Law/Procedure
Evidence
Real Property
Torts
Pennsylvania Essay Subjects
Civil Procedure (State & Federal)
Conflict of Laws
PA Constitutional Law (Rights of the Criminally Accused)
Corporations
Decedents' Estates
Family Law
Federal Personal Income Tax
PA Evidence
PA Rules of Professional Conduct
Sales
Employment Discrimination (Title VII, ADA and ADEA)
Partnerships
Limited Liability Companies and Professional Corporations
Wills
Trusts
PA DUI Law
plus all MBE subjects
plus the PA Performance Test (which this year was a client letter on an ADEA claim).
so that's a lot of subjects, but not impossible. i took NJ b/c you can't waive in later and i didn't want to be taking it in 10+ years like some of the firm attorneys and partners i saw there.
it really depends on whether a second bar admission is going to be useful to you. i honestly do not believe that taking a second bar exam adds a whole lot to your preparation commitment. i wouldn't say to do it for kicks, but if it will help your career, don't be afraid to take it on.
the biggest thing is to study and work steadily from the beginning; don't blow off late may and june. the people who do that are either brilliant or are freaking out in mid-july, and you do NOT want to be freaking out. the bar tests minimal competence; if you put in honest work in preparing and stay calm during the exam, you should be fine. go to class, then spend solid, quality time studying. maintain and schedule some personal relaxation time as well, or you will burn out.
and consider the video lectures; they're not any different than the live lectures, and you don't have to worry about offending a lecturer during a particularly boring session.
