Whether you are taking a bar exam in February for the first time or the fifth, the February exam is really no different than the one you might face in July. Sure, statistically there are more repeaters in February and the pass rates in some jurisdictions such as California can be a bit lower. However, as the July 2014 California bar exam proved with a less than 50% overall passage rate, statistics are meaningless if you do not distinguish yourself on the exam by putting in your best efforts studying.
When I took the bar exam in February 2010, I felt prepared but nowhere near as prepared as I wanted to be. I spent approximately 2 months studying in a professor's office on the campus of the University of Miami. The professor was on sabbatical that semester so I seized upon the opportunity to have a workspace that was not the law library or my home.
I also had a young child with special needs and I was taking two accounting classes at the business school. In other words, I was very busy just like you.
But what really made the February bar exam a challenge for me was my health condition. I was unaware that I was suffering from advanced stage cancer. Every day, I experienced back pain that was unlike any pain I ever encountered. It felt like someone stabbed me in my back. During the two days of the Florida bar exam, the pain was so intense, I thought that I would pass out while typing my essays or bubbling in Scantrons. It was only after the bar exam that I was diagnosed with cancer and spent four months undergoing three grueling rounds of chemotherapy.
In February 2010, I tried my best those two days of the bar exam. And when I learned that I passed, I was elated. If I can pass the Florida bar exam while suffering from cancer, while taking two business classes, and being a father to an autistic child, then pretty much anyone can do this.
Never give up and never get discouraged. You can always ask someone for help.
