Thanks! I remember the sinking feeling of looking at all of the fully booked courses, but definitely try contacting the organisers directly as my friend managed to get CCrISP within a couple of months that way.
Hi, I'm not too familiar with the applications process for CST in Ireland, but I recommend looking at the RCSI website. If you google CST Ireland application, then you'll find it and the application should be explained there. Best of luck!
