The title of this book is somewhat misleading. The book contains some useful studying tips but no secrets that you can't find elsewhere in a more concise, less repetitive fashion. In one passage he says successful A students study more than their peers, up to 10 hours per day, which is perhaps not most people's idea of effortless learning.
At one point the author claims that students who don't ask questions "remain uninformed of facts", "find it difficult to inspire teamwork and commitment", and can "hardly awaken the enthusiasm and zeal needed, eventually making one an introvert and a shy person". Their tendency to not ask questions "would exude them from getting the necessary information resulting in them always remaining ignorant and unaware of solutions and reality". While asking questions can no doubt be a worthwhile learning activity this unfounded overgeneralization seems tough to sell. Then he goes on to state that students should plan their questions "in a logical sequence", "phrase each question to maximize the information" received, and "predict all possible answers and prepare a smooth transition from each possible answer". Pretty sure I would never ask another question again if the goalposts were that high. When he continues to talk about effective questioning it's not always clear whether he's talking to educators or students. As a bonus he includes a gratuitous plug for a patriotic book by a former president of India, some unreadable mind map illustrations and several scientifically suspect statements about the brain.
A good proofreader could have eliminated grammar and spelling errors and unintentionally funny sentences such as this: "That's why when people have stroke; part of their body is parlayed because the brain cells are affected." I got this as a free Kindle book so it was well worth its price.
