For those specifically preparing for exams, the book also includes and solved previous year papers (such as GATE 2016) to provide a realistic sense of examination patterns.
A look at user reviews on Flipkart reveals a mix of praise and constructive criticism. On Flipkart, over 190 ratings give the book an average of 4.2 stars. The positive feedback highlights that the book is "simple and to the point," "very handy," and "wonderful". Many users find it excellent for competitive exam preparation, particularly for IES and PSUs. The systematic approach—presenting theory followed by relevant questions—is also praised. However, some reviewers point out that there are "many mistakes" or "printing mistakes," particularly in the answer key. A few users caution that the book is more suitable for advanced learners (e.g., engineering graduates) rather than diploma holders, as it can be challenging.
