Hi G., GED tests are $40 and you can go to the career center to take it. If you feel you need to review that's fine but it's easier than you think. It took me 10 years to do mine out of fear to fail and when I took it I was like that's it! The hardest was 2 geometry questions. Other than that it was reading and then answering from the paragraph and in the math 5 on division, multiplication and algebra ?'s. You can take out a ged book at any library and practice. I was so surprised when I opened the letter and happy that I passed. Remember your not trying to ace it just pass it. I then got the learning bug, got some computer classes all free at the career center, also interviewing, resume etc. Well in all I took 2 months to turn my life around and now 1 year and half later I will be graduating from college with an associate in science and thinking about a bachelor's. Time goes so quickly and the best part is your not thinking about all your problems. It's almost like everything falls into place. I also have 3 kids and found them a early learning center to go to. They (4c) help you pay for it if you work 20-40 hours a week and you could be self employed like services from your house or selling something. Good Luck and go for it your new life is waiting!
