I know it will sound terribly stupid but I'd like to know how do I leave the Oxenfurt Academy (the area around professor Shakeslock's house that is). I just can't go out by the same way I went in (with the help of Shani). I'm looking for a way to go out and all I've managed to do was to fall into the sea, to certain death. Doesn't help that Geralt is currently overburdened. Anyone knows how to leave this area? Thank you in advance.

THANK YOU so much. You saved me from many more hours of pure agony, heh. :)

I'd like to thank you too for this info. I feel quite silly having to search for help on this. I've got over 300 hours in the game and I finished the main story and I'm currently playing HoS and I don't think I've ever had to ask for help like this before lol. I spent probably ten minutes running around saying to myself "what the heck man". I was getting ready to jump off the top too. Thank you to my fellow Witchers for asking and answering this for me.
