Which font style is better to start designing fonts?

This summer I will have free time, and I'm very interested in starting myself in type design. I'm a graphic design student, and our typography teacher doesn't teach us to build type, just how to use it correctly.

So I'm wondering which font style is the easiest to start. I thought a script (maybe brush) would be easier because it doesn't matter if its a bit "incorrect" or some curves are not very good.

What do you guys recommend to me?
