I really liked the fact that Paul C found out where I was in the subject and built me up to where I needed to be. Paul C built up my skills in Math through his tutoring and I made an A in the class. I would recommend Paul C to anyone who needs a tutor in his area of expertise. Paul C will help you prepare for success and your grades will improve under his tutelage. Thanks Paul C.
Mr. C emailed us soon after our session with an answer to a problem my son had trouble with. I asked my son the next week how the session was helping him in his class. He said the things he learned from Mr. C really helped him with even the new topics they were learning. He feels much more confident in his class and said Mr. C is a great teacher. He doesn't give the answers, but teaches how to approach the problem to solve it. I highly recommend Joshua! He is AWESOME!
Thorough review of:
U-sub integration. Applying marginal revenue [cost] functions. Review of 1.2.1 thru 1.2.6 and the several practice problems for each of the six sections. Student notes already provided. Key skill: selecting 'u' so that 'du' appears in the original integral. Integral forms: du/u, u du, u^2 du, du/u^2, and simply integrating 'du'. Applying exponent rule for deriv-integrals.
