just keep at it like you did for your undergrad
By masters he means 4 years straight to masters. He doesn't have a Bachelors already.
Make sure you buy your books cheap off amazon marketplace. I usually get the current edition -1 and they work out at under a tenner each.
When you are at uni you have to understand that you are not being taught anything, they are just telling you what you have to learn. That's why you can have a lecturer with a really strong russian accent. They are just there to give you an idea. Everything that you will remember you will learn outside the lecture theatre in private study and it will reinforce what you have already learnt. Make sure you get in your private study, do any examples you receive and moderate your drinking enough to learn.
Don't drink to excess all the time and do not let women take over your life. Wash behind your ears etc.
Bob's your uncle.
