Hello, I am currently in my final year and having problems deciding what to do when I graduate. I am considering the Environmental economics masters course at Leeds.Will doing a masters course help me to get a better job in the future?

This is a very difficult question. There are certain masters courses which are gateways to particular careers or specializations. If the course you are choosing is not one of these then make sure it is one that combines well with your degree (i.e. is sufficiently different that it adds another string to your bow).
