Jack was simply a great tutor. I had struggled with CARS more than any other section and was scoring in the low 124 range consistently, which was tanking my overall score despite doing reasonably well in the science sections. Jack completely rebuilt how I approached reading comprehension passages we worked on active reading strategies, main idea identification, and recognizing the types of wrong answers that CARS loves to use. He was also meticulous about reviewing my full-length exams question by question, which was time consuming but eye-opening. My CARS score went up by four points by test day, and my overall score hit my goal. Clear, patient, and effective.
