Contact Professor Santiago if you would like to see specific technical and investment topics using short-to-the-point videos. The on-line videos are affordable you can view at your own pace.  If you would like one-on-one online sessions on a variety of technical topics, contact me at    

The course material is

  - Ideal for home schooling your family and for students  who are self-motivated
  - Serve as supplementary material to senior high school or university level education
  - Suited for professors or instructors who want additional and affordable resources & assets to supplement their teaching.

For those who need a refresher in math, I plan to develop video ebooks and  of a video-based online e-course in Introductory Algebra and a Trigonometry course.   Contact Professor Santiago for further details. 

I will also together as a coherent free public available domain material from video sites and For example, here's one where I've consolidated videos from YouTube posted by Standard University.  The course is entitled Fourier Transform and Its Applications.    In the layout, I would add lecture notes to follow the video lecture. 

Also, I plan to develop a collection of video clips and background references on the United States Constitution.  The course will be entitled, Freedom 101.  The previous link is my initial webpage if you want to see it evolve.  The intent is to provide a basic understanding on the original and founding principles the United States is based on.

Study in England GSE offers summer, semester, and year study abroad programs in London, England which allow students to study a wide array of courses with no language barrier.
