Software engineering class - High level tasks + sub activities +indent the sub activities + Gant chart

my teammates and me are creating a project plan for the topic below.

I need a high level tasks list and Sub-activities related to the high-level tasks

and also a Gant chart 

Topic: 

Education web platform which allows students to specify their desired degree and preferred University in order to determine the optimal course curriculum to graduate in the shortest amount of time. The platform would use GPS to identify near-by community colleges in which to augment the students schedule in order to reduce cost or time-to-completion. Additional pay functionality would allow a student to schedule course notifications, adjust classes based on personal preference, and pre-register at supporting Universities.

edit my high end tasks list, make it more realistic to my topic

add sub activities, and also create a Gant chart for everything.
