See if you want to select the correct option then you need to know the concepts and the procedures to solve it. So to crack JEE MAINS practicing question and giving mock test for time management is the main secret.

Now as per I understand your question, you are asking about guessing the correct option in JEE MAINS. See as you are a JEE Aspirant then you should know probability. The probability of correct option in a mcq is 25% if you are guessing. So random guessing can really lower up your rank as JEE MAINS have negative markings. So its better for you not to do guessing. But if you want you can predict answer logically. For example, you are asked to calculate the Energy in a certain problem. And in option there are four options which have units as Joule, Newton, Pascal, dyne/cm^2. Now you can predict the correct answer as the unit of energy can't be Newton, Pascal, dyne/cm^2 but it can be Joule. So the correct option will be joule.

But in JEE getting such question is really hard. So you should focus more on your preparation to crack the examination and it will be more probable for you that if you try to guess randomly then you will end up with a lot of negative markings.

Hello,

Some tips for mcqs are listed

Take a chance on one of the two possibilities.

If you've already marked out two wrong answers, take a chance on one of the two alternatives that has you stumped. Other recommendations, such as the first one listed above, might be used to help you choose your selection.

Using Numbers to Narrow Down Your Choices

Use this strategy for answering problems that need you to discover broad phrases for specific circumstances.

You are in the Safe Zone if there are no Negative Markings.

You are free to play if there are questions like "Match the Following" or other similar questions that do not have negative marking. Never leave a question like this unanswered. Examine the marking scheme carefully, as well as the directions on the question paper.

Values and Units

There are several questions that include units and values. Choose one of the three units listed, as well as the value that has been stated twice.

Questions that are more generalised

These are some of the most frequently asked questions by JEE administrators. They have a complicated orientation, and one of the variables must be found.

Just verify your selections again, assuming that two or more of the arbitrary numbers are zero, one, or any other simple value.

Co-ordinate Geometry Diagrams

Even if you don't fully comprehend a subject, sketching an approximation diagram to the provided scale will assist you in quickly calculating the radius, area, and equations. It may appear to be a little detail, yet it is quite effective in many situations.

Hope it helped

Good luck!!
