hey na you can do all those units .... because when you major in astrophysics . the minor requirement can be physics and mathematics too
here ive worked out a suggested pathway (you can change the chm units to whateva you like)... hope its right taking into account the prerequisites etc.
so sci/eng is 5 years and you need 240 points... 132 points being eng units and 108 points being sci units
