Don't get stressed out by the volume of work or getting an A. The sooner you accept the fact that you're likely going to get B's (less than 20% of 1Ls can get As due to the curve), the happier and less stressed out you will be. The workload can be overwhelming at times, but if you use the same study strategies you used in your undergrad you will get through it. However, be aware of your strengths and weaknesses and realize that you may have to change your study habits from your previous education if things aren't working. It definitely takes a bit of practice to be able to write decent summaries and exams! Definitely use old summaries as skeletons. I also really recommend planning your time very carefully- I use calendars and daily lists to make sure I've covered everything.
