I am applying for a paticular masters course, and have an application form, it asks for 2 references, but justs ask me there name, address, email etc.

would I just fill then, and wait for the person to reply without first telling, I understand lectures are'nt allow to give you a bad reference, just tell them about you, as a student!

Any help appreciated

Yes, always ALWAYS ask first! Whilst it's true that people aren't supposed to write a bad reference they are perfectly entitled to send it back saying that they are unable to provide a reference which will look very bad!
