Bruno Rodriguez has taught GMAT candidates since 2006. Lessons focus on understanding an error before assigning more work. Students learn to explain what they noticed, why they chose a method and how they will recognize the same idea next time.
The teaching standard
A correct answer can hide a fragile method. Bruno asks students to explain what they noticed, why the method applies and what would change the conclusion.
When a student works hard without improving, the answer is not more motivation. It is to identify the first repeated problem and focus the next assignment on it.
Repeating one solution may only show memory. Improvement means using the same skill later, on a different question and under time.
Private tutoring is not always the best route. If self-study, a course or another specialist is more appropriate, Bruno says so.
What students should expect
Students should know what they are practicing, why it matters and how Bruno will check whether it improved. More difficulty is added only after the current skill works.
A clear explanation of what is most likely holding back the score.
Practice selected to solve a specific problem.
Feedback on reasoning, pacing and confidence—not only accuracy.
A clear test for when the student is ready to progress.
No score guarantee and no pressure to enroll.
