It is the new type of quest coming with 0.6.7. You complete it at the Mansion, like upgrading house/smithing. Once the progress bar is completed, the 'Complete' button will appear. If it does not, you need to reinstall the base game without Extended Mod Loader.

I'm afraid I've only played these games on PC and I don't know anything about these games on android. I do hope you are successful starting Act 2.
Also story wise in Act 1; when I was given the option to become a college elite, I refused it every time. I've never tried accepting the offer before, I might start a new game just to see what happens. (Edit: refusing is required to play Act 2)
