I did the same thing. Do what you can and take the test when you're ready not according to an arbitrary time table you give yourself. Know that burning out can be due to the time given to all your obligations not just LSAT prep. If you work 10 hours a day and spend 4 hours on school then even a few hours of LSAT prep could burn you out before too long. Just trust your body and mind to show you what is workable for you.
