I am on my second semester of college and just turned 52! I am struggling with math also. I decided it was best to start with the very basic college math course and work my way up from there as I have forgotten most of the math I learned in school. It's much easier to refresh on the basics before attempting the actual algebra. It does take longer to complete the math requirements though.
Good luck in school, I have found that it is much harder now than when I was younger (but I am enjoying it much more). I don't seem to be able to concentrate or retain info as easily as I used to. I worked hard my first semester but I achieved a 4.0 average and made the dean's list - top 6% of the class!
