Study material is the most important resource in your preparation. Some students can prepare without any support of a faculty, but NO student can prepare WITHOUT a good study material. This post talks about the pros and cons of the various QA related self-studying options available in the market.

The study material available in the market can be grouped into 3 types –
Study Material of national level coaching classes (like Career Launcher, IMS and TIME),
Books that can be bought from a book-store (like Arun Sharma, Nishit Sinha, Sarvesh Verma),
Assorted online sources – Youtube videos, Forums (like Pagalguy) or FaceBook Groups (like iQuanta), Online Courses (like 2IIM, HandaKaFunda, Oliveboard, Unacademy, etc)

These different sources rank differently on the different aspects of self-study – Learning concepts, Practicing questions, Clearing doubts, Test Series. The following is my OPINION about the various options ……

Books from a bookstore

These are the cheapest sources (approx. Rs. 500 for complete Quant). And what you get is also the least (in comparison to other sources). The theory that is explained is mostly just solved examples or procedures (do this and get your answer). There is very limited elucidation of concepts. They are like traditional printed text-books, that get referred to after attending a class where concepts are taught/explained. Thus, for someone depending on self-study, these are not a good option to depend on for learning concepts.

Also needless to say, these sources rank abysmally on clearing doubts or test series. Then what goes for these books? Apart from the cost, two books (Nishit Sinha and Sarvesh Verma) have a good number and quality of questions for you to practice. So if you are well versed with concepts and want questions to practice, then this is the most cost-effective option to practice questions.

Which book?

The most popular book here is Arun Sharma (Tata Mcgraw Hill), because this is the book that started the trend of CAT-prep books. Unfortunately, the book has hardly any explanation of theory, very poor solutions to the exercise questions and is very lop-sided in its question bank (i.e. covers a few varieties that is totally irrelevant for CAT and lacks other varieties), has unusually weird questions in LOD III category. My personal opinion is avoid it.

The other two books that are popular are Nishit Sinha (Pearson) and Sarvesh Verma (Arihant). These books have a good number of questions for practice and cover a pretty wide range. The level of difficulty rises pretty fast in Nishit Sinha and many questions are twisted and turned needlessly to make them difficult. Having difficult questions helps in increasing sales, but may not be so relevant to exams. My personal favourite is Sarvesh Verma which has a good coverage of relevant difficulty and also few challenging ones.

Study Material of National Level Coaching Classes

These material win hands down in terms of their coverage and volume. The study material comes only as a complete package i.e. QA, VA, DI & LR (which I don’t view as any drawback, finally you have to do well in all three sections of CAT). The study material has levels – Fundamentals, Practice, Test Series. So the study material will suffice in your entire preparation journey.

This study material is built by a organisation – a group of people, rather than an individual. The organisation also has more resources to analyse the tests and update content regularly. Hence it has the accumulated wisdom of many and the strength of an organisation. So I find it surprising when books from a book-store are preferred over this source. The probable reason would be that these material require more money (ranging from Rs. 10,000 to 18,000). But this price also includes the Test Series (itself about Rs. 2000 to Rs. 8000), which you would invariably have to purchase if you are studying from some book off the book-store.

These offering also include some sort of online doubt solving, but I have not experienced it to speak about its efficacy.

Which one is better?

Both, Career Launcher and IMS, are pretty much at par, very little differentiates the two. TIME got very popular due to its Test Series. However it study material is the worst of the three as far as explaining theory goes. The so called Basic Study Material is just a show – list of formulae types, no explanation of any sort is provided. Also the questions in this Basic Study Material are very basic in nature. And then suddenly the level of questions in Practice Tests or Test Series increases to a very high level. Nevertheless, their Test Series is the most popular among the three. While in recent years, TIME Test Series has taken a beating due to its unusually tough or easy papers and CL and IMS has caught on with it, TIME Test Series still remains the most popular one.

Assorted Online Sources

The biggest drawback of these sources is that none of these provide a comprehensive & structured study material to practice. They have their advantages, but not for the ones struggling in their self-study. These sources are best suited for either those who rank among the top 5% (in prior knowledge of Quant) or who have already already exhausted other sources last year.

YouTube videos are mostly free. But then you waste time in sifting through the numerous available videos, most of them being incomplete in their coverage. And then the videos can only help you learn the concepts. They do not have anything to offer for Practice or Test series.
Online learning platforms like Unacademy or Oliveboard are woefully inadequate for CAT, as of now.
Facebook Groups or Forums score very high for what they are – social networks. You can discuss doubts, share good questions, talk to someone if feeling demotivated, etc. But will the Forum or Group act as a substitute for study material. Absolutely no.

Thus, none of these assorted online sources can be a dependable source for your planned methodical preparation. Don’t get me wrong – I am a big fan of online learning. E.g. I love https://brilliant.org. But that is for my love of Math. And I can learn online, it is very unstructured learning. Not everyone can. So these resources can suffice, provided you are already excellent in your theoretical knowledge or are a great online learner and can discern good stuff from useless stuff.

What is best?

IF YOU HAVE NOT JOINED ANY CLASSES and are depending on self-study, I think you do need a good set of study material from any one of the national level coaching classes (CL, IMS, TIME). Do not chase ‘quantity’. Take any ONE set and chase the completion of it.

While going through the study material, make use of online resources very judiciously – YouTube videos for learning concepts (just follow any one channel, DON’T click Suggested Links and waste your time), and Facebook Group or Forums for clearing the doubts (ask your doubt and get offline, don’t dabble in unconcerned stuff, now is not the time). Remember online resources are a time-killer. Get offline quickly (if your practice material is online, then close all other browser windows and focus on the pencil work on the paper at hand).

Plan to complete entire study material, except Test Series, by July. Once all the topics are studied and practiced thoroughly, now look for alternate sources. Simultaneously start the Test Series.
If you prefer being online, then participate in FB Groups and Forums. Solve questions posted there. Become social with other worthwhile active members, share question sets and approaches, etc.
If you are not an online person, pick up Sarvesh Verma (or Nishit Sinha). Solve the questions of the books as a revision round.
All this while your Test Series is going on.

That’s it. You can also consider our paid course as an option for self-study. We are too modest to suggest it in such an article. Please can get in touch with us if you want to know more.
