I went back to school in my late thirties, and it took me until this year to finish my B.S. in Chemistry. I went slowly, one or two classes at a time, with some time off here and there. It was difficult because I worked full time and had a family. My sone was 10 when I started. He is 24 now, and we spent this last year at the same school. I am 52, and feel that it would not be worth it for me to get a Ph.D because I would be so close to retirement by the time I finished. My company paid me money for school, and they are developing me, so that has been good.
Hi, I am also in this same situation. I am 33 finishing up my associates, then moving on to my graduate with time. I plan on it taking another 6 years to get to graduate level, with puts me at around 39 starting my graduate program. I also have a family to help support, though it is my wife, her mom, and myself at this time. I have also been worried, so it is good for me as well to see that others are doing this.
I am also a "lifelong learner". I am 41 and always love to learn new things, and have a deep interest in science and technology since I was small. I'd say studying is my hobby. I have a B.S. in Chemical Engineering and Masters in Business and experience in chemical industries (R&D and Management department). I also co-founded a school and have been teaching Math, Science, Chemistry, TOEFL. Last year I moved to the USA. For my career in the US, I took analytical chemistry courses (11 credits, lectures+lab) because ChemEng/ Chemistry are what I'm passionate about. It's nice to know all people who wrote here are like me.
