*asking advice* IB internship

So quite a simple question... for various reasons I am going into an IB internship, but beginning after the training week everyone else has had. So what are the hard skills you should learn for an internship?

Would be much appreciated from people that have actually done an internship. Basics I already have what you would/should know after finance degree.

I realise being comfortable with things like excel, powerpoint, creating company profile etc. and all the soft points

But asking about specific formulas you should learn- LBO's, certain things to include in a profile. Etc

Apologies if this has been done before- I can find lots about what tasks you may be asked to do, but little about how and what each task contains. Such as comps- but are there specific comparables that usually need to be modified before presenting to whoever your with?

This stuff is basic I know.... but I'm fearing I'll mess up on all the tiny things compared to everyone else that got some training.

To be honest I'm really bad at wording this. But if anybody who has done one could generally talk through what they did in a typical day that would genuinely be great. From a technical point of view (already read the famous moneymogul intern week write-up.
