3AC in May is unlikely to confirm due to onset of Summer season. Please keep checking your PNR. YOu MAY COME INTO RAC, AND POSSIBLY ONE/TWO BERTHS MAY GET CONFIRMED. Since you don't want to post your PNR this is the best answer possible. W/L1-4 have a good chance for RAC, but cannot say for certain for confirmtion of berths. 8th May also happens to be a Saturday, hence this kind of answer ... Good luck and good wishes.
