Do not spend any more money

If you are taking Barbri or any other course, you already have all the materials you need. Somewhere along the way, you will be tempted to take the Barbri Essay Workshop or some other essay workshop or a performance exam workshop. Fight that temptation! You really have all the materials you need between Barbri and the free past exams you can pull off of the CA Bar website. If you have the "extra" time to take the workshop, why not spend the time doing extra practice essays or taking an extra performance exam. Most of the people I knew who ended up taking these extra classes found it to be a waste of time and money.
