The Joint Entrance Examination (JEE) is an all-India common engineering entrance examination administered by the Central Board of Secondary Education (CBSE) for admission to engineering institutes across the country. It is also known for having one of the world’s most difficult engineering admissions exams. JEE is divided into two sections: JEE Mains and JEE Advanced. JEE Advanced is for admission to the Indian Institutes of Technology (IITs). In contrast, JEE Main is for admission to the Indian Institutes of Information Technology (IIIT) and National Institutes of Technology (NIITs) (NIT). JEE Advanced is only open to students selected in the JEE Mains.
Exam Pattern for JEE Main
The JEE exam is, without a doubt, objective. In a test, it’s critical to know whether or not you grasp the subject. It doesn’t matter how you do it as long as you circle the correct bubble.
Negative marking is used to prevent students from guessing incorrectly. However, if you can estimate wisely, you may never suffer a loss as a result of it. All tests, including IIT JEE, contain four possibilities for each question, and all of the answers are evenly split among the four options, i.e., a, b, c, and d. As a result, even if you mark all of your blind guesses, say option “a” the net difference in your score will be zero.
You don’t have to be astonished because the mathematical proof is right here. Assume you guessed in “x” number of questions and chose option “c” for all of them. According to the law of probability, 75% of your guesses are incorrect, and 25% are correct. As a result, your total is [(X/4) x (+3)] – [(3X/4) x (-1)] = 0. As a result, your score will be unchanged in the worst-case scenario.
The following are 9 tips for properly guessing MCQs in JEE Main.
1. Assigning a Value
You’ll see a lot of equations in the exam where you have to find the value of a variable. Try to swap the values given in the four response alternatives in these questions. Your right solution will be the one that solves the equation.
2. Stay away from extremes
When it comes to JEE Main MCQ techniques with numerical figures, avoiding extremes is key. Frequently, you will be given answer alternatives with a high and low value. The extremes are almost always incorrect replies. Therefore, it’s best to stay clear from them.
3. Unit and Values Tricks
Units and values are included in certain queries. In a question on heat and thermodynamics, for example, there are four options:
In these circumstances, the unit is usually mentioned three times, while the value is mentioned twice. As a result of the unit “°c” being cited three times and the value “50” being specified twice in the answer option, 50c will be the correct answer.
4. Analyze the dimensions
For the Physics paper, dimension analysis is a critical JEE Main MCQ technique. Consider a situation in which you must determine the value of speed. In this scenario, speed is the most important factor. As a result, eliminate any answer alternatives that do not include m/sec as a dimension. You will save time by using this method.
5. Assumption’s Trick
The assumption is one of the most simple and useful methods for guessing JEE Mains MCQs. When we use some assumed values to achieve the proper solution, it is often easier to solve an equation. The procedure is identical to that of replacement. In a trigonometry question, for example, you can replace it with any assumed value, such as 45°. This value can be applied to the given answer alternatives to solve the problem fast and easily.
6. Mathematical tricks for the “n” term
Math questions may require you to calculate the value, sum, or product of the “n” term. You must understand that the term’s value is usually 1, 2, or 3. Enter one of these values into the options provided and see whether you receive the desired result.
7. Choosing Between Two Alternatives
One of the JEE Main MCQ tactics is to gamble between two likely responses when faced with two possibilities. After you’ve ruled out the other two, you can try your luck with the remaining two by using either the approach of avoiding extreme values or the unit or value tactics.
8. Some Tips on the Subject
Identifying themes that can help you get the most marks is one of the most important JEE Main MCQ tips. It would help if you concentrated on the chapters on current physics that deal with atoms, nuclei, and radiation. These chapters take the least time to comprehend, yet they can help you score 20-25 points rapidly.
9. Focus on the NCERT Physics Introductory Chapter
For JEE Main MCQ techniques in Physics, a comprehensive understanding of the fundamentals is essential. At least 3-4 questions appear on topics such as approximation and dimensions. These are the easiest questions to answer and can get you points. As a result, make sure you go through your class 11 NCERT material thoroughly. Get a firm grasp of the first several chapters of Measurement.
FAQs on Guess Right Answer For JEE
Is it acceptable in JEE to guess the answers?
Nobody cares if you genuinely comprehend the ideas, cheat through the exam, or guess the answers. If they are proven to be correct, nobody cares! Negative Marking is a demon in JEE Main, JEE Advanced, and BITSAT to discourage blind guessing. However, making educated guesses can help you make the most of the situation.
Why is it critical in the JEE to employ reasonable guessing?
If they are proven to be correct, nobody cares! Negative Marking is a demon in JEE Main, JEE Advanced, and BITSAT to discourage blind guessing. However, making educated guesses can help you make the most of the situation. If you don't know the proper answer, making educated guesses will help eliminate all the incorrect responses and increase your score.
