/sci/ - Science & Math

As a future mechanical engineering student, It is my interest to know how much math, physics and 'computer' knowledge is needed in freshman year engineering courses. I am an 18 year old high school student and am worried about the very real possibility of not being prepared enough for university concerning a lot of things:

Advanced math courses: I have mastered algebra 1-3 using a textbook. Poor background in Geometry and Trigonometry. No background in Vectors.

Physics courses: Absolutely no background aside from what school taught me(to which I attentively paid attention to and got high marks from). I need to develop background using SELF-TAUGHT knowledge.

Programming: Absolutely no knowledge at all.

I still have 2 years to prepare (going to enter senior high school, 11th grade in 2 months)
