In this blog I have shared with you the** Pdf of SHORT TRICKS** below. Just go through it and you will be able to solve question within few second.

### Hit and Trial

It is a fundamental trick that you can use to solve problems with the general solution. Start with putting values to the variable and check which of the options give you the answer. This JEE Main trick will fetch you easy marks and is suitable for problems that sport complex orientation.

### Remember the Series Expansion

Most of the problems in JEE Main Mathematics have a quick and neat solution that does not require more than a few lines. The well-known methods for such problems may be cumbersome and time-consuming. In a few cases, series expansion may come in handy. Keep them in the back of your mind.

Also, it would help you a lot if you practice trigonometry and its related formulas during the last few months of your preparation. Look up the formulas frequently, so that you don’t forget them. Deriving these formulas during exam time will be futile, and nothing will serve you better than your memory.

## How to Make an ‘Intelligent’ Guess

JEE Main does not require you to submit any working or procedure of how you arrived at your answer. It only awards you on the merit of your choice. As a result, there is a scope for intelligent guesses.

Personally, I would not advise you to rely completely on guesswork if you wish to crack the JEE Main! But at times, a few correct guesses can boost your rank a long way up.

### Stay Away from Extremes

Some of the questions in JEE Main have numerical answers. In such cases, it is often a good idea that you stay away from the maximum and minimum values. In almost 65% of cases, the answer would be one of the two closest values.

### Narrow Down Your Options

At times, the options can be very confusing. In such scenarios, you can systematically strike out those options which are completely unlikely. Questions that have ‘All of these’ as one of its options can be approached by eliminating the wrong choices, thus, reducing to only two viable possibilities.

### Units and Values

Another common shortcut you should use during your JEE Main exam is examining the unit and the value of each option. JEE frequently plays around with it. If you are stuck on a similar problem and solving it seems out of the question, choose the unit and the value with maximum occurrences.

### Dimensional Analysis

Dimensional Analysis can help you out in some of the most terrible situations. Not only will it save you a large chunk of time but will also steer you away from possible mistakes you may commit during tedious calculations.
