school work

Its great to be at work ^^
At least of the perspective I got a lot of material for my school task.
My boss is the best, he helped me to choose the "perfect project" to study and the project manager gave me all the documentation I might need to explain what It was all about.
Now my only worry is...In my company everyone talks/writes and communicates in emails in English..so It seems that the easiest way out of my problem with having all documents in English is to write the entire paper in English aswell.
Its a bit scary..I mean yeah Im pretty used to the talking and writing but not you know this really correct English while publishing stuff.
well this isn't to be published anyway, its just gonna be me and my teachers reading it but still.
It needs to be right.
On Monday my teacher and I have a booked teleconference so I'm hoping to be able to ask her then about this. Until then I just read and read..no writing.
