Yes do it - you can only stay the same or gain from it.
BTW you have missed the first few weeks of college, unless you have expected to get in and snuk in to lectures already (yes iv done it). This makes it quite difficult missing any time especially the first few weeks where introductions to all cources, choices, rescources and people are missed out on. If you already have one or more friends in there you should be ok. otherwise start goining in tomorrow to lectures. you wont be noticed anyway.
On the other hand if your trip to athlone is unsuccessful
Repeating is not the end of the world. You will be more mature, more educated, and more able for the course next year!
If you like to gamble (which i do!) Take the year off- try to get a job in the field you want to work in - check it out for a while. if all goes your way then the points will come down by 5 on hey you are in otherwise
you are up that chocolate creek without a popsicle stick!
