I was a pre nursing student. I have made A's all the way up to Statistics and Algebra 2. I have made A's and B's in all my science courses including Anatomy and Physiology etc... please email me for serious inquiries. Ghane1@umbc.edu. I have math tricks that will make your life much easier and good mnemonics for Science classes. Depending on the course...I charge anywhere from $30 and up a session. My job is to make sure you know the material before I leave. I don't do it by hour. Because If if takes me 2 hours to teach you something...thats not your fault. If I have to look at sample problems your teacher wrote to make sure you are doing it the way they want...I feel you shouldn't have to pay for that.
