Arun Sharma DILR Books: What They Actually Cover and How to Use Them
I have spent years watching students treat the DILR section as either a mystery or an afterthought before they hit the books. The data handling and logical reasoning portion is consistently the most unpredictable segment of the exam, and it rewards a very specific kind of practice. Arun Sharma has written a set of books that target exactly this gap, though they are not perfect for every single student. The primary title most people look for is the quantitative aptitude book that includes a dedicated DILR section. It covers the standard puzzle formats: linear and circular arrangements, seating arrangements, grouping, blood relations, direction sense, set theory, and data interpretation through tables, bars, lines, and pie charts. It also handles more complex setups like flowcharts, networks, and Venn diagram applications. The questions range from straightforward to genuinely tricky, which mirrors what appears on the actual test.

Searches for a free PDF of these books show up constantly across forums and Telegram channels. The reality is that the books are copyrighted material, and most of those links are either broken, contain malware, or deliver corrupted files. I have watched students waste hours downloading files that turn out to be incomplete scans or versions missing entire chapters. The legitimate sources are the publisher's website, major retail platforms, and college libraries. If cost is a genuine barrier, many university libraries carry copies, and secondhand copies circulate frequently on student groups at a fraction of the original price. My observation is that the DILR section requires a different study method than the rest of the quant portion. You cannot simply read the solutions and move on. The method is to pick a set, give yourself four minutes, and if you cannot identify a clear path to at least one sub-question within that window, you move to the next set. After the mock, you go back and attempt the ones you skipped. This builds a decision-making habit that matters more than solving every single problem perfectly. Most students skip this step and just attempt everything, which burns through time and leaves them with partial scores instead of a clean selection. The book organizes its material by difficulty level: basic, moderate, and advanced. The early sets teach you to recognize patterns quickly. The moderate tier forces you to handle multi-step puzzles where one wrong assumption cascades into three incorrect answers. The advanced tier is where the actual exam difficulty lives, and these are the sets that separate students who clear the cutoff from those who do not. A common mistake I see is students grinding the easy questions until they feel comfortable, then never actually progressing to the harder material. That creates a false sense of readiness.
I had a student once who was consistently scoring in the 85th percentile on full mocks but stalled at the DILR section. The problem was not knowledge. He knew how to solve a seating arrangement puzzle. He could not decide which puzzles to attempt. He would spend twelve minutes on one set that had a trap in the third sub-question, miss an easier five-minute set, and then panic on the final block. We stripped away all the timing pressure for two weeks and made him do only the selection exercise: scan three sets, choose one, and commit. The improvement in his sectional score was immediate because the bottleneck was entirely strategic. One counter-intuitive point about these books is that the answer explanations are sometimes longer than the optimal solution path. The author often presents one complete method, which is pedagogically sound, but in exam conditions you need to recognize the fastest route. I found that annotating the solutions with my own shorter approaches while reviewing helped more than passively reading the provided explanation. Writing your own path forces you to compress the logic, which is exactly what you need under time pressure. There are also legitimate limitations to be aware of. Some of the older editions contain question patterns that have shifted away from what the exam currently favors. The examiners have moved toward more application-heavy interpretations and away from pure mechanical arrangement puzzles in certain years. If you are using an older edition, cross-reference with recent mock papers to verify the patterns are still relevant. Another limitation is that the DILR section rewards speed of recognition, and the book alone does not build that. You need timed mock attempts alongside the chapter practice to develop the four-minute decision rhythm.

The advanced sections of the book assume you are comfortable with basic arithmetic, percentages, and algebra. If those foundations are weak, the higher-difficulty sets will feel impenetrable, and you will lose time wrestling with fundamentals instead of learning the DILR strategy. I recommend spending a week or two reinforcing basic calculations before diving deep into the advanced puzzle sets. It cuts the frustration significantly and makes the later material much more digestible. For students on a tight budget, the most practical approach is to borrow a copy from a senior or a library, work through the basic and moderate sections thoroughly, and supplement with free online mock tests that replicate the actual exam pattern. The advanced sets are valuable, but they are not worth pursuing at the expense of solidifying the foundational puzzle types. The marginal return drops off once you have a consistent base of recognizable patterns. If you are preparing for the exam and want to study the same material, purchasing a used copy or borrowing from a peer is the most straightforward path. The content remains useful regardless of the edition year, and the DILR strategy itself does not change dramatically between recent versions. What changes is your ability to make fast, confident choices under time pressure, and that comes only from repeated timed practice with immediate review.
