About Guillermo

Chemistry major all the way ( undergraduate and graduate). I have been a lab instructor in college for several years, especially tasked to handle Honors Sections. I have been recitation classes instructor in several major chemistry courses. I am using Zumdahl, Chang, Brady, Brescia, Silberberg, Oxtoby and Tro books for general chemistry. Consistently solves problems on AP Chemistry and SAT Chemistry books from Kaplan, Barron's, REA, McGraw-Hill's and Princeton's after they are out in the market. I am using Morrison and Boyd's, Carey's, Brown's, David Klein's, McMurry's, Wade's books in Organic Chemistry. Taught students around the area from Pepperdine to UCLA to different CSU campuses and local community colleges around the area. Please don't be left behind too far back in your lessons. Remember that information/concepts and techniques in problem solving are cumulative in Chemistry.
