Hello
I just want to drop this with you. Do all u ve to acquire a system and find out what branch of computer science you can major in, after all you've significant places that must have held your interests when you were still in school be it software development, human interface, artificial intelligence, robotics, and so on. when you have determined your focus field, then go ahead and procure materials that will assist you know more on it and how it can interpreted to assist in this present world. Armed with that knowledge of yours, get the GMAT and other aptitude texts and start practicing. This will help you with mathematics and logics which are required for your course of study and fear not. Just because you left school to raise kids doesn't mean you can't get a job or use your course to be something. Read wide and remember Cecilia Ibru, a good and worthy example of what you're going through right now.
All is well, just remain focused.
