Hey guys, I'm a current 2L at Hastings, and I just wanted to share my experience with people in this thread in case they find it helpful.
First, congratulations to all who were accepted! I'm super happy that I decided to attend Hastings (I was choosing between here and Davis), I've really enjoyed my time here, and I think my life is better for it. Anyone with questions please feel free to PM me!
Second, I wanted to address anyone who was on the waitlist about questions you might have, because I was actually accepted into Hastings off of the waitlist.
Here is my experience: I was placed on the waitlist about 6 weeks after I applied. As others have noted upthread, the admissions office specifically asked not to spend in additional correspondence, so I didn't.
Then, in late May/early June, the admissions office began to send out emails specifically requesting letters of continued interest. These came in waves (so I got a email dated 5/20, or around then, asking for a letter of continued interest, then two weeks later another email saying "You said you were interested on 5/20, but are you STILL interested? If so write back again!"). After I replied to the second wave of emails and stated I was still interested, I received an offer of admission from Dean Canada via telephone.
So, to sum up, you don't need to send a letter of continued interest until after Hastings asks you to, and once you send one, keep your phone with you!
Finally, just to share, I was a super-splitter, my GPA was like 2.4 (or something, don't recall), but my LSAT was 175. I went to an undergrad that didn't differentiate between "punitive" and "non-punitive" withdrawing from a class, and I had to withdraw from an entire semester, so the LSAC helpfully averaged in an entire semester of Fs into my GPA, killing it.
However, once in at Hastings, I've done very well and so far my future looks good. Again, let me know if anyone has any questions and feel free to PM!
