Hi kate!
Welcome to the community!
Nice little introduction
Are you a UK based med student then, or from somewhere else? Hope it's going well 
Well, we've got various articles here for MTTs and SnG's, so I'll link you to both!
MTTs
SnGs
Both of these will be helpful to you, even if the SnG ones are tailored slightly differently! But maybe one of the most important articles for while you're learning poker is one about bankroll management
We also have videos for you to watch, just set it to the type you want and have a look what there is to offer 
And one more important question - Have you taken our quiz to receive your free $50 on one of the starting rooms? If not, I suggest you do!
You'll then start receiving strategy points, which help upgrade your status at PokerStrategy.com, so you can read more advanced articles here to help give you the edge to crush those fish 
If you want to know anything more, give us a shout.
Best regards,
Jim
