HELP LAUREN GRADUATE

Hi, My name is Lauren and I'm currently looking to graduate highschool and get a job so that I can help support my family and (hopefully) go to university. I havent been to school in over 5 years (since 2014-5) and I currently am unable to enrol in a "normal school" as I dont have the grades/report cards for it. I learnt about the GED & SAT testing last year and ive been doing my best to study for it ever since, until I researched more and actual realized that each GED test cost $75, an SAT test is $100+ which all in all is $450+ and that is Way way out of my familys budget. I would try to get a job and pay for this all myself but.. I really cant do anything without any sort of diploma and im really looking to getting a job as soon as I finish the tests so I can get a job and start taking care of myself & my family all while saving up so I can enter uni. Any little bit helps, Thank you.
