Enjoy uni, try to get an interesting and decently paid job then go back to dad and Mum's and start saving money for your training.
I first flew in 1999 and started my training 10 years later so there is no rush mate.
And forget about integrated vs Modular it is all the same, just organised differently. I am integrated but if I were to start again I would definitly go modular and save 10k (maybe 20k).
Good luck, take it easy now is the perfect time for studying!
