Dr. Wang's Exam Style

Dr. Wang provides one practice exam for his students to study, but no past actual exams. Tutor with me for access to 3.5 semester's worth of Dr. Wang’s exams and explanations dating back to 2017 when he started teaching CHEM 237, CHEM 241 and CHEM 247 to prepare you for the midterms and final.
Contact me for regular tutoring ASAP, and I can show you where Dr. Wang sources his exam questions, what he emphasizes, and what he excludes from your textbook.
Dr. Wang is not a “fancy professor.” Meaning that he is a creature of habit, does not assign unnecessary homeworks, and sticks to the same mechanisms/reactions on midterms 1, 2, and 3 each semester. However, since Covid happened, his format could change in Fall 2021.
His exams always contain a Wittig Mechanism and Intramolecular Claisen which tend to be worth a lot of points. The reason why I can state this online is because it’s seared into my memory from my tutoring experience with students in his class. Tutor 1-on-1 with me to find out which other reactions he favors!
