## 4 tips to solve IIT JEE questions faster

The debate of hard work vs smart work will never end. But what we can conclude is that a combination of the two will definitely yield positive results.

While preparing hard for JEE, some smart work during your preparation can definitely help you solve questions faster during the actual exam.

Here are 4 tips shared by Hardik Verma, a HashLearn tutor from BITS Pilani, Goa.

1. Value Substitution – Often when the question consists of a term with multiple x’s and y’s (or a’s and b’s) and you have to reduce it to a value, just put some numbers in place of x and y and check out the options. One of the options will match. For example, if the question says that x, y, z are three numbers in GP, put x = 2, y = 4 and z = 8.
2. Dimensional Analysis of Options – Sometimes in Physics (and also in Chemistry) there are options with different units. In this case, just do a dimensional check of the question. It will match one of the options. This is the correct answer as dimensions cannot change in an equation.
3. Using Graphs – This trick is restricted to Maths. In questions where you are asked to find the number of solutions to two equations, or to find the range, you can very easily do this by drawing the graph of the equations without actually finding out the solutions.
4. Stretch Guessing – This one is only applicable to exams which have some questions without negative marking. It is applicable to some questions in the JEE Advanced. Five minutes from the end of the paper, make stretch guesses on non-negative marking questions that you were not able to solve. What is meant by stretch guessing is marking the same option for all questions. So, for example, mark B, B, B, … for every such question. If you don’t get any right, you don’t lose anything. But if you do, it’s a bonus for you.
