Recent Tutoring Session Reviews
"We discussed Gas Thermodynamics. We quickly reviewed the Maxwell-Boltzmann distribution and the RMS speed. We discussed how to understand Graham's Law rather than memorize it. We then reviewed the 2 previous formulae for Work that we had discussed, and introduced a new one for the Work done by a gas. We defined Pressure, and discussed the new equation in terms of units and zero-analysis. We next discussed the 1st Law of Thermodynamics, and showed why the commonly-taught reformulation is doubly-bad and limiting. We reviewed the work done by a gas in expansions and compressions. We reviewed the sign relationship between the Works on/by, and system/surroundings. We next defined adiabatic gas processes and how to recognize their occurrence. We then defined isobaric and isothermal processes by comparing them to adiabatic processes both verbally and pictorially. We discussed work and heat as energy transfers, and the 3 types of heat processes. We discussed how to graphically interpret p-v graphs, using the Carnot cycle and an example problem to discuss the skill qualitatively and quantitatively. The student is still differentiating Temperature from Heat in her mind, but with repetition and practice problems, she will surmount this obstacle. Pressure is still a little difficult, but a post-session wrap-up and review seemed to firm up the relationships between these concepts in her mind. The student will review the PDF, and review the website. We will discuss Chemical Kinetics and Equilibrium next time."
"We worked on sentence completion, reading comprehension, and a variety of math subjects. Overall the session went well. We are working on building vocabulary and strategy for the verbal section."
"The student and I had a very productive math session today, where we began our review of the GRE Quantitative section. We went over basics and things to remember before we got started and then began reviewing math concepts, along with strategies and tricks to work out problems faster. Accuracy and the importance of scratch paper were of course foremost! We went on to review the math sections that the student proactively completed before our session. She did pretty well. As an update, the vocab app seems to be working well for the student, which is great to hear! I will now be sending her my 100 most common word list, as I think she'll be able to breeze through it. I will also be sending her sets of math drills as homework for our next session. I was happy to see that she is understanding everything well so far and is also honest when she doesn't know what's going on. We will spend our next session doing the rest of math and recapping on vocab."
