I started doing a computer science course 3 years ago at uni but changed a yr or so ago and am now in the final semester of a design course (where i am "taught" maya )

Like you I couldnt decide which path to take and ultimately I chose the wrong course at first

Research both options mate and speak to potential lecturers. In any case, If u do decide once u start a class that its not for u - nobody can stop u from changing onto another one!
