How did you learn what works for you? Did it magically click at some point?
I learned what works for me around mid-October. My school has midterms for 1L's. Once I got my exams back, I knew that my study habits were not working. I later found that I'm an auditory learner. I learn best when I listen to others teach (study partners) and when I teach others. Also, I retain information by talking aloud. At this point, you should know how best you retain information which is 50% of the work. The other 50% involves testing your analytical skills by taking practice exams. (both timed and untimed)
I would suggest taking practice exams around mid-November. The KEY which people often miss is to show your practice exams to someone credible. Preferably your professor during office hours. If this is not an option, visit academic support, or any other resources available to 1L's at your school. After showing a practice exam to my contracts professor, he actually told me the grade he would have given me had it been an actual exam response. It wasn't what I wanted to hear so I kept making appointments with him until I finally got an A out of him! Of course, not all professors will be like this but the point is to have someone look over your practice exams so that you know you're on the right track.
ALSO, it's best to find out what works for you early on, even if it takes a little experimenting...are you a visual learner, auditory, a little of both? Do you get distracted easily by outside noise, do you talk when you write, do you find that you vividly remember what you hear as opposed to what you see. This all might sound crazy, but once I found out how to master the first half of the law school exam equation, I was well on my way!
