1) No one knows for sure when to expect the second wave. Last year the acceptances were mid november, mid december, end of january, end of february, then more frequently march + april. The mid november wave has gone out, itll probably be right before christmas that the next wave does (though this is only my guess)
2) Baylor accepts more students per wave as the cycle goes on. It is likely that the class is not very full right now.
3) No. All interviewees are considered during each wave (barring the interview on the week of the wave)
