Advantages of starting CAT prep early
A video on the advantages of starting your CAT prep early enough. Watch the video to know what is early and why you should start early. The brief idea is ... 1. Earlier you start, smaller is the duration you need to study each day and hence better is the concentration. Also the relaxed pace of learning allows you to indulge in the topic/question. You can learn the subject more inquisitively rather than just being in a hurry to tick off having competed a topic. 2. By starting early, even if you stray off the course for some time, the repercussions are not disastrous. It is very common for students to lose focus and then CAT prep takes a back-seat. Often students have mailed us asking us how 're-start' their prep. By starting early you can afford such
Time needed to study a topic
You want to plan your CAT studies? Not sure, how much time needs to be planned for a topic? This is the ultimate guide for the time needed, based on different scenarios - if you are starting early or starting late, if you are a fast learner or a slow learner. Go ahead, plan. And more importantly, put in those hours of study. Guide_to_time_needed_publicDownload
CAT ’21 Early Start Study Plan
Study Schedule of our first batch of CAT 21, with Live Online classes, is finalised. Have a peak into December's schedule below. Starting early has a big advantage – you can take your days easy and enjoy the learning more. Starting early also allows you to catch-up if you have missed studying for a day or two in between. Contrast this always lagging and trying to make-up for lost time and I am sure you will appreciate the advantage I am talking about. So, all you have to do is firm up your mind and get started with the batch. Everything else, we have chalked out for you, right to the minutest details, as you can see below ... And the course is presently available at the cheapest price. Read about/Enrol in the course here.
Approximating roots of cubic polynomial
It is almost a standard question, to start. Later it turns out to be difficult. Your approach should be to factorise the polynomial .... p = 1 results in f(1) = 1 – 7 + 6 + 12, not equal to 0 p = –1 results in f(–1) = –1 – 7 – 6 + 12, not equal to 0. p = 2 results in f(2) = 8 – 28 + 12 + 12, not equal to 0 p = 3 results in f(3) = 27 – 63 + 18 + 12, not equal to 0 p = 4 results in f(4) = 64 – 112 + 24 + 12, not equal to 0 We should realise that for no further positive natural values, will f(x) be equal to 0. If you dont know why, read further, the reason will be clear. Now analysing the polarity(+ve or –ve) of f(x), [...]
Divisibility Rules for 9, 11, 99, 101, 999, 1001
Extend divisibility rule of 9 & 11 to 99 & 101. And why to add & subtract alternate digits or groups of 2 digits.
Comparing difficult fractions
You can do the following ... 1. Compare pairwise, but select appropriate pairs to eliminate a few 2. Among the ones left, judge which of the following two approaches seems easier ... ... is % changes in numerators (and denominators) easier to estimate ... or is numerator, as a % of denominator easier to estimate. Follow the easier out of the two. 3. Then there are some cool manipulations you can do (explained as the last point in this post) I will use the given ratios to explain the above. Say we need to find the greatest of 1089/1375, 1086/1430, 1144/1562 and 1110/1636 Step 1: Between 1089/1375 and 1086/1430, the first fraction has higher numerator (than second) and smaller denominator (than second). Thus, first fraction > second one. So second one is eliminated. By the same reasoning, 1144/1562 > 1110/1636 (bigger numerator and smaller denominator) We are left with comparing [...]
RC Live Classes (with a pinch of Summary/Essence and Complete the Paragraph)
So here it is, finally! RC Live classes. In these live lectures we are going to learn to solve RC passages (and summary/essence and complete the para) in a time-bound manner and to the best of our abilities. Please remember that this is a practical series, and so you need to have watched my videos (freely available on YouTube here). I will refer to the theory a lot and will even revise it if time permits. But you should watch these videos as soon as you can. Initial couple of lectures will be free for all, and after that it will be a paid course. Not too much though! The format: A day before the lecture I will send a couple of passages for you to do and then in the lectures I will solve your problems or do the entire passage if majority hasn’t understood it. And in the [...]
∆ with integer sides, given perimeter
Based on the the following doubt asked at facebook ...... Find the number of triangles with exactly one side odd and perimeter = 203. The question is a little too lengthy for CAT. Yet it does allow you an opportunity to build approach & stamina when detailed lengthy work is involved. Approach 1: You would need to know that the number of triangles with perimeter = p is ..... .....\(\left[\frac{p^2}{48}\right]\), for p being even .....\(\left[\frac{{\left(p+3\right)}^2}{48}\right]\) for p being odd where [x] is the nearest integer function. Since perimeter is odd, the total number of triangles = \(\left[\frac{{\left(203+3\right)}^2}{48}\right]\) = \(\left[\frac{206\; × \;206}{48}\right]\) = \(\left[\frac{103\; ×\; 103}{12}\right]\) = \(\left[\frac{10609}{12}\right]\) = [884.0833] = 884. These will be triangles with (1 side odd & 2 even) or (all 3 sides odd) If all three sides are odd, say (2a - 1), (2b - 1) and (2c - 1), then(2a - 1) + (2b - [...]
Food For Thought 38
Love the news but hate clickbait and fluff? Here’s how to get more quality and less quantity Feb 5, 2019 / Cal Newport Digital minimalist Cal Newport shows how you can turn off the information firehose and follow current events on your own terms. Are you ready to join the attention resistance? In 2010, a trio of Germans with backgrounds in sociology, technology and market research posted a document titled “Das Slow Media Manifest” (the English translation is “The Slow Media Manifesto”). Following the Slow Food movement — which promotes local food and cuisine as an alternative to fast food — the Slow Media Manifesto notes that the first decade of the 21st century “brought profound changes to the technological foundations of the media landscape.” The second decade, it proposes, should be dedicated to figuring out the “appropriate reaction.” More here
