Dr. Rodriguez's Exam Style

Dr. Rodriguez's exam questions usually combine 2-5 or more concepts into 1 problem. Reverse problems are common where students must solve them backward. Not all questions are straightforward, and you need to translate "English" into "numbers or formulas."
Most CHEM 271 exams are designed for students to finish, or answer accurately, but usually not BOTH at the same time.
Exceptions-to-the-rule in chemistry and organic chemistry are frequently shown for the first time on exams or briefly mentioned during class, but with no examples.
Contact me for regular tutoring ASAP, and I'll help you determine where Dr. Rodriguez sources his exam questions, what he emphasizes, and what he excludes from your textbook.
