It’s easy to become overwhelmed by the amount of the material on the bar exam. There is a lot to recall, and a lot to practice. Just take it step by step, one piece at a time.
Whether you are taking the bar in July, September, or October, you still have a ways to go. Instead of thinking that you need to learn all of Constitutional Law, learn equal protection, due process, dormant commerce clause, etc. Break each subject up into topics, and take it one topic at a time.
That doesn’t mean that you have to master each topic before moving on to the next, you don’t. It just means that breaking the information into smaller pieces will be more manageable to learn, and will help you better assess your progress.
Keep pushing forward. Do practice questions every day. You’ve got this!
