What Choti Book By Rosomoy Gupta Bangla Choti Part 2 Actually Covers

The second part of this book picks up where the first volume leaves off. It deals with more advanced arithmetic and algebra shortcuts that are commonly used in competitive exams in West Bengal and Bangladesh. The material covers topics like surds, indices, quadratic equations, profit and loss variations, time-speed-distance tricks, and basic geometry shortcuts. The presentation is in Bangla, which makes it accessible for students who think through problems in their mother tongue rather than translating from English. I picked this up back when I was helping a cousin prep for banking exams. The layout is dense. There are no filler examples. Each section gives you the shortcut formula first, then two or three problems, and moves on. That efficiency is what makes it useful, but it also means you cannot skim it passively. You have to work through every line. The approach in this book relies heavily on pattern recognition. Instead of deriving each solution from first principles, it teaches you to spot the structure of a problem and apply the matching shortcut. For example, when you see a pair of quadratic equations with coefficients that are multiples of each other, the book walks you through the factorization pattern instead of the standard discriminant method. That saves roughly 40 to 60 seconds per question on a timed test. Over 60 questions, that adds up to something substantial.

One thing most beginners miss is that the shortcuts assume a certain baseline fluency. If you do not already know your multiplication tables up to 25 squared and your cube values up to 15 cubed, half the tricks in this book will slow you down instead of speeding you up. I learned that the hard way during my first mock test. I spent more time trying to recall whether 17 squared was 289 or 290 than I would have spent solving the problem normally. My workaround was simple: I wrote out the multiplication and power tables on A4 sheets and taped them to the wall. I reviewed them for ten minutes every morning for two weeks. After that, the shortcuts started working as advertised. Another common pitfall is that the book sometimes skips intermediate steps. It assumes you can fill in the gap between line two and line three on your own. During a practice session on surd simplification, I hit a problem where the answer appeared out of nowhere. I traced it back and realized the book had rationalized the denominator and simplified in one invisible motion. I spent twenty minutes stuck on that single problem until I rewrote the step explicitly. Now I go through each example with a separate notebook and write out every intermediate step myself. It takes longer initially, but it prevents false understanding. The geometry section is probably the weakest part of this volume. The shortcuts are narrow in scope. They work for standard triangle and circle problems that show up repeatedly in exams, but they break down the moment a question introduces an unconventional diagram. I ran into this during a mock test when a single question involved an inscribed angle combined with a tangent-secant configuration. None of the shortcuts applied. I fell back on first principles and solved it normally. For those cases, you need a separate reference book that covers Euclidean geometry from the ground up. This book will not help you there.

If you are using this material for exam prep, here is a realistic workflow. Spend one week on each major section. Do not move ahead until you can solve the practice problems without looking at the formula sheet. Time yourself. If a shortcut is taking you longer than the standard method on average, drop it and go back to the conventional approach. The book includes around 200 to 250 short-cut problems across all sections. Working through them at a comfortable pace, with active recall checks, usually takes about three to four weeks total. Trying to rush through it in five days will leave you with surface level familiarity and no real retention. The most practical use of this book is as a second layer of preparation. If you already understand the underlying concepts from a standard textbook or classroom instruction, this volume sharpens your speed. If you are starting from scratch, it will frustrate you. The Bangla explanation style is direct and assumes you already know why the shortcuts work, not just how to apply them. Pair it with a foundational resource and the results are solid. As for getting a copy, search for it on local Bangla book retailer sites or third party marketplaces that operate in India and Bangladesh. Physical copies circulate through college bookstores near educational hubs in Kolkata and Dhaka. Digital versions exist in PDF form across various forums, though the quality of scans varies and some editions contain misprinted numbers. Always cross verify a suspicious problem against a second source before building your study routine around it.

The book has real value if you approach it correctly. It is not a comprehensive math guide. It is a focused collection of shortcuts for specific exam patterns. Know what it is and what it is not, and you will get good use out of it.
