the age question
Just to add my thoughts to this.....
33yrs is approaching the limit in my opinion. I was 33 when I started, 35 when finished and now fly with ezy. It was tough getting my first break, but persistence does pay off. If you are going to do it, i would do it as soon as possible. Lots of people say that age isnt a barrier, but my experiences conflict this. I went through oxford, and the older guys and gals had more problems securing work than others. they did not secure me my work.
As for int / mod, in my opinion it depends on your discipline and finances. Integrated if you are not disciplined as you will be pushed along at a fast pace wether you like it or not. Modular is at your own pace.
