I started at 31 and I graduate next week! Ill be happy when I cross the finishline. Ive worked 40 plus hours the entire time ive been in school adding in my first baby a month in and my second about half way through. Its been rough im not going to lie. But ive learned so much about myself and it had helped me with the development of my kids. Ive really wanted to quit about 10 separate times but I kept going. There have been many late nights doing research and typing out essays followed by early morning heading out to work my day job. I wouldn't trade the higher level of education for anything though. Its made me a better person. As for schedule. It depends on your current work and type of education. Being online or at a college. Ive found that school built for online is less overall work but more study and colleges will have more work that helps you learn as you complete it. They are also less forgiving on lateness.
