  TIP OF THE DAY  
 
On this page you can see the 20 most recent Tips of the Day.
While practicing sums, learn to derive the formulae that are going to be used rather than memorizing them. Deriving formulae helps one to be prepared for logic-based sums that cannot be solved by standard formulae.
 
While eliminating options in RC questions, look out for options that contradict ideas from the passage. Even if part of the option contradicts a certain idea, the option can be eliminated on the basis of being partially incorrect.
 
Questions that involve variables in multiple equations can be solved to get unique values for variables. However, at times, the question only requires you to reduce the equations into a different form, one that is representative of the answer. Avoid time-consuming solving of equations whenever possible.
 
Questions based on vocabulary can also be solved using an analytical approach. Analyzing the sentence in which the word is used can give clues towards finding the contextual meaning of the word even if you do not know the dictionary meaning of the word.
 
In verbal sections, when you have narrowed your options down to two and are confused between the two, it makes sense to mark one of them even though you might not be sure as the probability of getting it right is half whereas the negative mark, if you get it wrong, is much less than half.
 
Data sufficiency questions are generally yes/no questions where the statements have to be analyzed for their sufficiency in solving the problem. It may not be necessary to solve the question and to get the answer.
 
It is not necessary that the summary of a passage should be a single sentence. Do not use this criterion for eliminating options while solving questions related to summaries.
 
In a triangle, the sum of any two sides has to be greater than the third side. Also, if the sum of the squares of the two smaller sides is less than the square of the third side, the triangle has an obtuse angle.
 
Style of a passage is defined as the way in which the content of the passage is presented to the reader whereas tone is a reflection of the author's attitude while presenting this content. Thus, style is related to writing style whereas tone is related to written content.
 
To keep your concentration levels high throughout the entire verbal section, try splitting it into two sections - RC and non-RC questions. Try and do something that is more mechanical in nature (for example, DI) in between these two sections.
 
While selecting questions to solve, do not go by how the question appears. Read the entire question carefully before taking a call on if it can be solved and how much time it would take to solve it.
 
Retaining information and facts from the passage is very important while solving RC questions. Pay special attention to building your retention skills while practicing RC. This can be done by preparing a mental summary after reading every passage and before answering the questions succeeding them.
 
Make sure that you have read the entire passage before answering questions based on main idea. A half read passage may lead to a bias towards some options and make you ignore the other options.
 
If all the coefficients of the different powers of x in an equation are positive, the equation does not have any positive root and if all the coefficients of even powers of x of an equation are of one sign and all the coefficients of the odd powers of x are of the opposite sign, the equation does not have any negative root.
 
Glancing through the entire section before solving it is useful, as it gives an idea of how the questions have been spaced out across the section. This helps in cutting down the time that goes into flipping pages and searching for the right question to solve.
 
The formula for calculating permutations is used when the order of the selected items matters while that of combinations is used when only the number of selected items matters, they may be selected in any random order.
 
Statements that have non-quantifiable words like beauty, strength, failure etc. are classified as judgments since these parameters cannot be measured and hence are beyond the scope of being stated as facts or being drawn as inferences.
 
In DI questions involving pie-charts, the degrees of all sectors should be converted to percentages as most of the questions revolve around this conversion. Also, while converting all degrees into percentages in one go, the chances of making calculation errors reduce.
 
Identifying the central idea of an RC passage is very important as most of the supporting ideas revolve around this one basic idea. Also, while solving the questions, a correct understanding of the core essence of the passage will enable one to easily identify all the incorrect options that contradict it.
 
The relative speed of two objects is given by the sum of their speeds if they are moving in the opposite direction and their difference when they are moving in the same direction.
