Joined data science course but I feel it is wastage of money. Only limited items are taught and rarely practice on code. Coding is mostly executed by trainers and HTML file for code will be shared. Only Vaishali Balaji is good trainer which takes classes for Python for data science and Machine learning. I would not recommend to take simplilearn. I have taken partial refund as one of my colleague was offered the same course in lesser fee. Would suggest other options to learn data science. Most of the reviews are positive here since discounts are offered for other courses. So be aware.
