I had a great experience with Prep Expert, and my instructor, Nirmal Karthik, was absolutely amazing! He is incredibly patient and thorough, explaining concepts clearly no matter how many times I asked questions. His teaching style made a huge difference, and I saw a significant improvement in my practice SAT scores after taking his course. I really appreciated how he made sure everyone understood the material before moving on. The course structure was well-organized, and I felt very prepared for the exam. I would definitely recommend Prep Expert to anyone looking to boost their SAT scores!
