Importance Of Clearing Doubts

Importance Of Clearing Doubts

Edited By Ramraj Saini | Updated on Apr 18, 2024 04:55 PM IST | #JEE Main

A saying attributed to the ancient Chinese philosopher Confucius goes like this: “The man who asks a question is a fool for a minute, the man who does not ask is a fool for life.” If you are having doubts, it means you are making efforts to learn something new. We can understand the importance of doubts and their timely resolution by looking at an example. Suppose there is a wooden stick. You can break it easily. Now if we make a bundle of sticks and try to break them together, then it would be very difficult to break the bundle. In a similar way, doubts become very difficult when they pile up. Asking doubts or questioning is the basis of understanding, mastering, learning, and knowledge creation. Science starts with asking questions and seeking the answers.

Importance Of Asking Doubts

Sometimes, when the teacher is teaching a concept, you may not understand it. This can happen because you did not ask the right question due to fear. But there is nothing to regret about asking a question because questions are asked in the exams based on the same concept that you did not understand. So, it is good to clear your doubts early.

Decreases Negative Marking

Exams like JEE Main, JEE Advanced, NEET, etc have negative marking when you answer the questions wrongly. That is one of the major reasons why so many students are not able to obtain good marks. During exams, we get confused because we don't have clarity about the concepts or we have doubts. If we have discussed our doubts in class, then we can answer the questions correctly. We can save ourselves from silly mistakes and decrease negative markings by asking the right questions and clearing doubts in the class.

Helps To Develop An Interest In The Subject

Some students like Math, while others like Social Science or Science. An important advantage of building interest in a particular subject is that you are getting clarity in that subject. In other words, you are clear about your doubts and have a good grasp on concepts so that you are able to solve questions. The habit of asking doubts attracts the focus of the teacher and creates a fear within you that the teacher can ask you questions, and to prove yourself in front of the class, you start investing time in that subject, and it develops a circular loop. You end up with an interest in that subject.

Broadens Your Knowledge Horizon

Sometimes you are asking and discussing it. That helps broaden the horizon of your concepts, knowledge base, and logic. There are multiple methods to solve a question. For a particular case, one method is easy but it can be difficult for other cases. When you ask your doubts, teachers try to explain comprehensively using different ways that broaden your understanding. You also think again and try to find all the possible variations in the question and create their own database, concepts and tricks that broaden your horizon.

Helps To Master The Subject

Asking questions or doubts is the central point of knowledge creation and learning. If you want to answer a doubt, then first you require a good understanding and mastery of the subject and related concepts. It requires a lot of practice and hard work to master the subject.

Fuels Creativity And Scientific Knowledge

Questions are fuels for innovations, scientific knowledge, and creativity. We are aware of the story of Newton, he was sitting under an apple tree. An apple was falling down when he asked himself why it was falling downward then after he proposed the universal law of gravity. That is the power of asking questions or having doubts. Asking questions increases your creative and scientific thinking. This also facilitates your analysis and diagnosis of your knowledge base.

Helps To Develop Interpersonal Skills

You can observe big personalities like businessmen, entrepreneurs, politicians, IAS officers, etc. who are good at interacting with people, asking good quality questions or doubts, and can express themself on stage and in front of thousands of people very confidently. Sometimes people judge you on the basis of your doubts. This habit of asking good questions and having doubts helps you develop these interpersonal skills. If you want to be like them, you must have these qualities.

Time-saving and building a strong foundation

It is important to support students when they voice their doubts. Instead, the goal should be to save time and obtain more insightful responses to your questions. When an expert or teacher answers questions, it goes beyond simply answering questions. The student receives several added values, such as learning multiple ways to solve a problem, memorisation techniques, shortcuts, and suggestions for better reference material, which can save time. It can also be helpful while giving exams, as students have time limits for the exam.

Your concepts gradually become clearer if you continue to ask questions and get your doubts cleared from the beginning. And without wasting time learning the underlying principles, you will be prepared to grasp a complex concept.

It Makes You More Confident

Our confidence increases when we have a good grasp on concepts. After asking doubts, you become more clear about concepts and logic because your mind becomes more focused. This makes the concepts last long time in your memory. When similar questions come to you again, you will be confident and able to solve them very easily. This is because you are asking questions and answering correctly in class, which makes you fearless. That helps to build a good image among the students and in the class.

Helping Others

There are other students who also face the same difficulties in grasp the concepts; they also have doubts but do not ask due to peer pressure, hesitations or fear. Your habit of asking doubts helps other students understand the concepts, develop an interest in the subject, obtain good marks, develop interpersonal skills, decrease negative marking, and make others confident.

In the present competitive world, you have to compete during board exams, entrance exams like JEE Main and Advanced, NEET, and other exams. To crack these exams, you should remove every doubt at the earliest possible time because it becomes very difficult to clear them when they pile up and can be a disaster for you.

There is no requirement to have Physics, Chemistry, and Math (PCM) in 12th to appear for JEE Mains 2025. You must have passed the class 12 exam in 2023, 2024, or 2025 .You need to have studied at least five subjects in your qualifying exam, with Physics, Chemistry, and Mathematics being mandatory. This means your PCB combination fulfills the Physics and Chemistry requirement.

Since you haven't studied Math in 12th, you need to put in extra effort to build a strong foundation in Mathematics, which is a crucial subject for JEE Mains.Qualifying for JEE Advanced, which allows admission to IITs, requires Mathematics at the 12th-grade level.

I hope it helps!

Alliance University Bangalore doesn't specify a single entrance exam for this program on their official website. Here are the possibilities:

  • Alliance University Scholastic Aptitude Test (AUSAT): This is the university's own entrance exam. It's a possibility for admission to various undergraduate programs, including engineering.

  • JEE Main/Advanced: These national-level engineering entrance exams are widely accepted by many universities in India. While not explicitly mentioned, Alliance might consider JEE scores for B.Tech. programs.

  • Other State or National Level Engineering Entrance Exams: Some states might have their own engineering entrance exams, and Alliance could potentially accept scores from those as well.

  • Merit-Based Admission: In some cases, Alliance might grant admission based solely on your Class 12th marks (depending on availability of seats).

No, directly floating your choices to get a higher preference in subsequent JoSAA counselling rounds isn't guaranteed.

JoSAA uses a demand-filling process. In each round, it allocates seats based on candidate preferences, institute/branch choices, and candidate ranks.

If you don't get any of your higher choices (including your 1st choice) in a round, and a seat is available in one of your lower choices (like your 4th choice), JoSAA might allocate that seat to you.

However, there is no guarantee that your 1st choice will become available in later rounds.

During the second round (or any subsequent round), you'll have the option to either freeze your allocated seat (4th choice) or float it. Floating means you're willing to give up your current seat for a chance at a higher preference in the next round.

If you are happy with your allocated seat (4th choice) and don't mind attending that college/branch, you can lock it (freeze). Consider how likely it is for your 1st choice to become available in the next rounds. If the seats for your 1st choice are filling quickly, floating might be a gamble. You might end up with no seat at all in the next round. Floating involves some risk. You might lose your current seat (4th choice) and not get your 1st choice either. Locking secures your current seat but eliminates the possibility of getting your 1st choice.

I hope it helps!
