Mario A.

Chemistry Tutor and Writer (ENG-ESP)

Do you need help with General Chemistry, Organic Chemistry, Inorganic Chemistry, Physical Chemistry, Biochemistry, or maybe Math and Physics? I'm a Chemist, in the middle of getting a Ph.D. in Chemistry Technology, and with extensive experience helping both students and organizations reach their goals. Got a Chemistry problem? I have the tools to help you! I've written practice materials and sample questions for tests under GCSE and NGSS standards, and I know the inner workings of many standardized tests such as the MCAT, SAT, and GAMSAT. Not only I know how to apply univariate and multivariate data analysis, but I'm also proficient in interpreting and communicating results from Instrumental Techniques such as FT-IR, GC, IC, UV-VIS, AA and ICP under international standards (ISO 17025). I have experience with tutoring students as a Tutor and a Teaching Assistant in several subjects, and I'm able to communicate complex science concepts and analysis results using simple and catching language. I also have written over 50 Laboratory Reports during the course of my career, with academic and technical style. I'm passionate about using statistical tools to help solve problems in everyday life and especially in STEM fields. Ask me how I can use them to solve yours!
