(4.0/5)
"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) "
"I took the course of Lean Six Sigma Green Belt with PD Saha. The course went well, ran on time and the workload/time management was fine. PD Saha was prepared and able to answer all the questions/doubts. Overall, I would suggest the course and the trainer."
