What should I learn?

Hey Guys,

I wasn't able to secure a FT in IB because of my lack of internships, according to what interviewers said, and I've managed to get an internship at a very small IB for the spring quarter. Now this isn't a typical internship where it's a 10 week program. They are going to have me help them doing some work where they need done and in return teach me whatever I want to know. I know the very obvious is tell them to give me experience in modeling, creating a DCF etc, what my question is what should I ask them to teach me that I will be able to put on my resume to show that I have the "skill set" to try to apply to boutique IB's for off cycle analyst hiring?

If anything was unclear please let me know and I'll try to rephrase.
