Requirements for Cal grants?!?

Hi there! I have q's about the requirement of cal grants. What is the minimum Gpa require? How many units do I need to qualify? I went through high school and graduate with a 2.89 gpa. And I went to community college for 1 year and I didn't do anything so my gpa is 0.0 and I decided that I need to change my life. So I'm currently going to MTI college, it's a less than 2 yrs program, to be a phelbotomy. And I took about 3 terms already and I have about 28-32 units completed and my gpa been 4.0. My parents r divorced n my mom is a single mom without child support holdin up three teens. So we are a very low income family. My mom barely make $7,000 a year. So which cal grants will I qualify/apply for? What are the minimum gpa require? And how mny units do I need to apply? And how should I apply? Ps. My financial Ed told me to go back to my high school and filed it. But he doesn't knw I been out of school for over 2 years now. So please someone help with these questions! And please don't tell me to chck the website!!! I already did and they didn't provide with any of the questions I asked. Thanks alot!!!!
