What Our Learners Say About Us
"It's a good learning experience with Pritesh! He spent time to help me going through both 7th and 8th edition and giving exam tips. Appreciate it!"
"Fundamentals session was good. I would prefer a more fast pace."
"In terms of content, all good. But poor time management. Time expected for breaks was never compliant (ie. if teacher said he was taking 10 mins break, it ended up being 20. For 50 mins break, teacher was showing up AT least 10-15 mins late...) Also, during second day I asked one question about a test and teacher seem disappointed for me to ask and gave me a whole speech of me not retaining all information while reading (after hours of exhausted training) also letting me know people who does not focus tend to have Low IQ... Also, having to spend time just waiting for teacher to end notes that I guess it should have been ready already for the lesson (at least, if the teacher is expecting for the alum to memorize and know everything at once) "
"It was good experience "
"Pritesh has good experience and knowledge on the subject. Had a wonderful learning experience."
"I loved the course! The instructor was great—they pointed out essential details I should pay attention to and shared some valuable notes that will definitely help me with the upcoming exam."
"Useful content, great learning experience!"
"I had a great two days of training with Pritesh Shah. He was very patient with teaching the proper terms and providing real world examples for better understanding. I was the only one in the class and I felt very much accommodated to my learning style and how I can absorb information better. Every question I had was explained thoroughly to me."
