I was not good in math in high school because I did not apply myself. I believe I had an attention deficit. I was always preoccupied about my mother dying. However, I did pass my math classes -2 without any remedial work. What I did do though was a lot of practice before I did my placement. I went to the thrift store and found a workbook and text book that accommodated it and practiced,practiced and practiced. I took a two week refresher course before taking my placement test and I was placed into an intermediate algebra class and then went on to finite math. I was so proud of me because I had not been in a math class in almost 16 years.
Use several text books from the library, thrift store or look at Amazon or Ebay for books (cheap but good). When I did drug calculations in the program, I always passed the first time - I would do over a hundred problems a couple days before each day and it was a good thing. Math was not my bag but I passed and you can too.
I will share what my Finite Math instructor shared with me and it encouraged me. Stop saying you aren't good because you will start to do your math that way. Here goes the story.
My math teacher was in the military or either retired and he taught on Saturday mornings. How I did so well in his class is because he was motivated and together. He wrote every thing using all three boards for his schedule. His alarm was set on his phone when it was time for the next phase and when we had breaks and the end of class. His voice was like a coach or driller but he was personable and encouraging.
He told me that when he was in elementary school, by 5th grade they told his parents do not let him think of any jobs/careers using math because he would not make it. He in return encouraged himself as David did in the Bible and made himself learn by applying himself and began to like it enough to become a math instructor. When I went to him saying the same thing you are saying about my inability, I was encouraged.
Also, my daughter was good in math all through school until middle school. She and an instructor clashed and she had to repeat it and her math went down hill thereafter. However, in high school I encouraged her to take all the math and science she possibly could because I screwed up in high school because I literally took a teacher at her word. Back then an adult's suggestion was golden always. She would say when someone was acting up in class "If you aren't doing good now in Algebra 1, don't come to me next year for Algebra 2." Why did I feel she was talking to me. I was making C's and it was kind of boring and I was preoccupied that my mother was going to die more than any thing. To get to the point, my daughter entered college and had to take remedial maths 2x. We thought she would never get out of remedial math. She wanted to be a nurse and she changed after A&P 1. Then she transferred those credits to a CIS program. After 99 years almost, she decided to change her major again to ACCOUNTING. Why? Because she found a job that taught her financial budgeting as an admin asst. and she has an awesome resume reflecting millions of dollars that she handles for large companies - some have been fortune 500 companies. The phone rings off the hook for interviews and she has not completed her Bachelor yet. Her starting salary is better than mine and I had been in the gov for 20 years.
YOU CAN DO IT TOO! PRACTICE, PRACTICE AND PRACTICE WHILE YOU ARE HOME ALONE. CLOSE YOURSELF IN A ROOM LIKE I DID WHEN FAMILY IS AROUND AND YOU HAVE SPENT TIME WITH THEM.
GOD BLESS YOU AS A NURSE
