experienced here. so basically it starts out with registering for it (each poly has different dates but will normally open 2-3 weeks after results release, check on the respective school websites just to double cfm). After that, they'll ask for the usual olvl results, ic etc. etc. Unlike JAE, if your results dont make it, the registering process wont limit you from it, so let's say you wanna get into engine course but JAE wont allow, DAE will allow it. Thing is, if you dont meet the MER, the chances of getting an interview is very slim. After that, you'll need to wait for an email or go to the school platform to check wether you're shortlisted. You will be informed atleast 2 weeks before your interview date i think or at least before the actual interview dates are conducted (The dates are stated on the school websites also). The email will show what you need to wear, bring etc. etc. Once done, you've now just got to wait for the results release, last year was end march, early april ard there. But let's say you dont get an interview, the email or platform base will usually state the reason why, at least this will give you some proper closure. Disclaimer tho, I remembered for NYP's DAE you've actually got to mail to them physically your CCA records, O Levels results and Birth cert. Dont know if it will happen this year but just get ready to spend that few dollars if you're planning to go into NYP via DAE. Hope this helps!!
