im doing a property economics degree... because its quite specific a lot of the property companies/a-reits come directly to the uni to poach undergrads....
however this has changed now cause of the cred crisis...
i was lucky to get in this january before we knew the full extent of the problems...
so depending on your course, the uni usually helps you a bit with contacts...
also look at the companies that are in your field, look at applications for undergrad/grad programs... however usually for like a job to start in February, applications close the previous June.... so think ahead
