Hi, I did not attend law school online but I did work 20 hours a week during my 2L and my 3L years. I honestly wish that law school took 2 years, like MBA programs, I do not see value to the third year. Tuition is a huge rip off and there is little practicality to what you learn throughout all the 3 years. I think what matters is that you have to seperate academia from your profession. Obviously, study hard and get good grades. But, more importantly, look for practical experiences and do not allow studies to get in the way of making personal networking connections and doing real work. A lot of people may think that when you are in school, you should not work. I find the opposite to be true. As you go through school classes, it is even more important to work in a real life setting. I would encourage you to look for something outside Staples that has legal skills involved.
Finally, as far as studying for the bar exam goes, the only way to do that is to simply dedicate 3-4 hours a day in the span of about 2 months where you are studying, with no distractions. The bar exam study process is like a download into your brain of information which you likely will not need, and which you will forget rather quickly. That said, you need to get through it. It is no different than any other standardized test and it is by no means an objective way to assess how good you would be as a lawyer.
