I didn't set a standard number of hours but I used Becker which was a 4 week course and I studied for an extra week so 5 weeks total. I went to all lectures, did all the homework and repeated questions I got wrong until I got them right and then did a progress test after each section (i.e. sections 1-2 after homework for 2, sections 1-3 after homework for 3, etc) and then the two practice tests at the end. I was probably studying 4-5 hours a night and then one full day each weekend, and a full weekend at the end. Hope that helps! Good luck with your score! Fingers crossed!
