The best you can get!

For sure the experience of studying in DCU is the best you can get so far!
All the staff there was really helpful from the very first day till the day I left Dublin for the last time. The accommodation they got me was comfortable and secure, the facilities were great including football pitches, a complete sports centre with swimming pool and all the rest you may need and a pub with good beer and food.
I've spent one and a half year there and attended both English course and University. These two experiences were quite different but great in different ways.
On the english course the lessons were funny without losing content and the teachers committed with all the students. There were useful extra-classes like "Job interview" and "Conversation" classes, with the two best teachers ever. The IELTS preparation course is also a powerful point of the experience.
On the other hand, during the University time things get a bit more serious as you may expect, but the social life improves as well. There were great classrooms, labs fitted with everything you need to study and a complete library.
No regrets at all! I highly recommend DCU!
