"but if i don't get doing architecture and i do architectural technology instead......who knows......i might even like it and just become a drafter or something"
I don't even know where to begin on that one....
I think JB was trying to say years 1-3 are level 7 and if you pass that you can do year 4 which is level 8.
You always have the option of doing architecture, I know people who came at it as mature students from backgrounds in IT, secretarial, accounting, etc.
Coming at it from tech may not necessarily be that long, the standard route is 4 years tech then 5years arch, skipping the year out becuse you'll be, well, old. But I know a few people who finished top of their class in tech, worked for a year in a top level architects office and were then allowd to skip first and second year and in some cases even third year architecture. But those cases are quiet exceptional.
But I've said it before, and I think it is especially true in this case since you are talking 4 years time minimum, and since you apparently don't yet full grasp what you are talking about ("a drafter or something") I would strongly advise you to stop asking stupid questions, these quesions will be irrelevant if you just keep the head down, the leaving cert is not that hard.
