I used to studied in Hertfordshire,UK. I manage to use 10 pound for a week. eat and cook @ home. Save alot. As for working, you chances to get a permenant job is quite hard as for IT Grad. for engineering, then is diff case. If you study civil engineering, then ur chance will be higher since they going to host olympic, they need alot of engineers there.

As for part time job, the pay is quite good. for example, my friend worked in Tesco during holiday, they paid 7 pound per hour. but work like the bangla here. hahahah.
