Which is your favorite lesson to teach?
Data Sufficiency, no doubt. I love the hungry looks my students get in their eyes when it suddenly clicks and they realize they can use the GMAT's traps against it. The Princess Bride routine I do as part of it? That helps, I'm sure, but it might just be to keep us all entertained.

13th Ed, SC #133
I really like teaching Sentence Correction because it's the one place in Verbal where significant strides can be made by learning a few key grammatical concepts. This problem does its best to hide its classic 3/2 verb agreement split by switching up the continuous/non-continuous aspect (not a concept tested on the GMAT) in the verb decision point at the end of the underlining. Once you notice that split, it also does its best to hide the subject behind a raft of modifiers, but again a simple rule (the subject you're looking for won't be found in a modifier unless the verb is part of that same modifier) helps us get rid of tempting plural candidates nets, devices, and laws to find the correct singular subject compliance. From there it's relatively obvious.
So what I like is that this problem is very easy for someone who has mastered two of the key skills we teach: identifying the good decision points and identifying the proper subject for a verb. And yet for someone lacking those two skills it's fairly difficult. I find that while many students want to improve on Verbal, deep down they need to be sold on why they should relearn (or in many cases learn for the first time) basic grammar instead of just relying on their ears. And this problem does a good job of showing them.
Real reviewsEthan turns the cold, pragmatic GMAT into a humorous foe
Ethan took me from a 610 to a 690. I have learned from Ethan both in a group and one-on-one setting, and in both he is phenomenal. If you want an instructor who adjusts based off of your learning style, reinforces both the technical and strategic sides of the GMAT while keeping the material engaging, he's your man. Ethan turns the cold, pragmatic GMAT into a humorous foe by using examples from life and film. After working with Ethan, you won't be able to watch The Princess Bride without thinking of Data Sufficiency... and that's not a bad thing. I went from being nervous and self-questioning on my first test to relaxed, optimistic, and (I didn't expect to say this) EXCITED on my final test day.
Ethan was a phenomenal teacher.
Ethan was a phenomenal teacher. He genuinely cares that you learn, and more importantly, retain the material. Everything was very well structured and easy to follow. I highly recommend this class to anyone looking for GMAT prep.
Ethan was amazing
Ethan was amazing, and made the material very digestible. His strategies are working and I can tell that he has spent a lot of time thinking about incorporating his style with the material (very polished).

My favorite GMAT lesson to teach is Critical Reasoning because this area really represents the crux of what the GMAT is about. The GMAT is truly about problem solving and using the information the test makers provide in various ways to help solve the problem. Students that are able to think critically are able to solve problems more effectively.
Which movie/TV character would do best on the GMAT and why?
Obviously, that would be MacGyver. The GMAT is just like an episode of MacGyver (without the explosions) where the student plays the part of MacGyver and must quickly solve problems using the any and all the tools at their disposal. Like MacGyver, the student is often tasked with coming up with a solution to a complex problem using seemingly tools and information in creative and unique ways.
Real reviewsCould not ask for more in an instructor.
Dennis was flat out amazing. He took every opportunity available to make sure we understood the material presented. He was flexible with his time and his approach. Could not ask for more in an instructor. Give this guy a raise!
Dennis is the kind of once-in-a-lifetime teacher that you truly appreciate.
Dennis is an extraordinary teacher. He took the time to explain everything in a way that each person in the room understood - if someone didn't understand it the way he said it the first time, he would go about the problem another way until that person was on track with the rest of the class. He went above-and-beyond, coming to class early to make himself available for extra help, staying after class if some of us were still struggling. He really personalized the classes to suit our needs and addressed each of our problem areas. Dennis is also funny and easy to get along with! He joked around with the class, made us feel comfortable, and it is obvious that he truly enjoys what he does for a living. Walking away from the final class, I was talking with another student, and we both expressed that we wished Dennis would be our professor for all our grad classes once we get into our MBA programs. Dennis is the kind of once-in-a-lifetime teacher that you truly appreciate.
Dennis Cashion was one of the best instructors I've had.
Dennis Cashion was one of the best instructors I've had. He made himself available outside of class, gave us personalized attention in the class, and was overall one of the best at conveying information of any GMAT instructor, I've had.
