Math
I've been studying higher math on my own, and also at local colleges, and I spend a lot of time on Khan Academy (my profile is here). These pages show a proof of the work I've done.
Update: 25 June 2015 (Completed Calculus III, Differential Equations, and Linear Algebra)
From January to June 2015, I completed Calculus III during the Spring semester and Differential Equations and Linear Algebra during the Summer semester. I really wanted to get the math requirements behind me.
24 December 2014 (Completed Calculus II)
Calculus II went well :-) I found it very difficult and stressful but, I managed to pass now I'm moving on to Calculus III.
Concepts I practiced are:
Volumes Using Cross-Sections
Volumes Using Cylindrical Shells
Arc Length
Areas of Surfaces of Revolution
Work and Fluid Forces
Moments and Centers of Mass
The Logarithm Defined as an Integral
Exponential Change and Separable Differential Equations
Integration by Parts
Trigonometric Integrals
Trigonometric Substitutions
Integration of Rational Functions by Partial Fractions
Integral Tables and Computer Algebra Systems
Improper Integrals
Solutions, Slope Fields, and Euler's Method
Indeterminate Forms and L'Hopital's Rule
First-Order Linear Equations
Sequences
Infinite Series
The Integral Test
Comparison Tests
The Ratio and Root Tests
Alternating Series, Absolute and Conditional Convergence
Power Series

Areas and Lengths in Polar Coordinates
Vectors
The Dot Product
22 August 2014 (Completed Sections 7.1 to 7.4 "Integration Techniques" - Calculus: Early Transcendental Functions by Roland Larson)
Calculus - Chapter 7 work PDF file
Since this has been going so well, I decided to enroll in Calculus II at a local community college so I can get college credit for what I've learned. Being officially recognized as an aerospace engineering student has some advantages compared with going it alone (eg. access to internships), Section 7.4 was as far as I got before my class started.
Concepts I practiced are:
Basic Integration Rules
Fitting Integrands to Basic Rules
Integration by Parts
Integrals Involving Powers of Sine and Cosine
Integrals Involving Powers of Secant and Tangent
Integrals Involving Sine-Cosine Products with Different Angles
Trigonometric Substitution
12 August 2014 (Completed Chapter 6 "Applications of Integration" - Calculus: Early Transcendental Functions by Roland Larson)
Calculus - Chapter 6 work PDF file
Concepts I practiced are:
Area of a Region Between Two Curves
Area of a Region Between Intersecting Curves
The Disc Method
The Washer Method
Solids with Known Cross-Sections
The Shell Method
Comparison of Disc and Shell Methods
Arc Length
Area of a Surface of Revolution
Work Done by a Constant Force
Work Done by a Variable Force
Fluid Pressure and Fluid Force
Mass
Center of Mass in a One-Dimensional System
Center of Mass in a Two-Dimensional System
Center of Mass of a Planar Lamina
30 July 2014 (Completed Chapter 5 "Transcendental Functions & Differential Equations" - Calculus: Early Transcendental Functions by Roland Larson)
Calculus - Chapter 5 work PDF file
Concepts I practiced are:
Using the Log Rule
Integrals of Trigonometric Functions

Review of Basic Integration Rules
22 July 2014 (Completed Chapter 4 "Integration" - Calculus: Early Transcendental Functions by Roland Larson)
Since Khan Academy doesn't have their Integral Calculus course complete yet, I pulled out my old Calculus book from college. The last time I attempted to learn Calculus, learning Integration was what stopped me. Just really didn't get it and certainly couldn't apply it to anything. This time I was happy to note that it all made much more sense to me this time :-)

The Integral Calculus course on Khan Academy isn't quite fleshed out yet. Many parts are just videos. If a section only had videos, I skipped over it.
