Avoid These Mistakes in Board Exam | Common Mistakes by Students

Summary

In this video, the speaker highlights common mistakes that students make during board exams and offers practical advice to avoid them. By showcasing real examples from students' work, the speaker emphasizes the importance of accuracy in calculations, maintaining the correct order in geometric proofs, and writing out steps clearly. The video stresses that simply copying answers without showing the process can lead to losing marks, and the key to success lies in understanding the concepts and avoiding early mistakes. The speaker encourages students to stay diligent and proactive to secure better exam results.

Takeaways

• 😀 Start solving questions correctly to avoid losing marks from the very beginning.
• 😀 Avoid copying answers directly from textbooks or others, always write your own steps.
• 😀 Make sure to remember important values, like trigonometric values (e.g., sin, cos, tan) to prevent mistakes.
• 😀 Double-check the order of steps in geometric proofs and mathematical problems to ensure accuracy.
• 😀 Writing out each step in your solution, especially when unsure, can help secure marks.
• 😀 Be mindful of the relationship between HCF and LCM, and use the formula correctly (HCF * LCM = First number * Second number).
• 😀 Pay attention to the specific angle values in trigonometric problems to avoid errors.
• 😀 Mistakes in the starting steps of a problem lead to a greater loss of marks than mistakes made later.
• 😀 Teachers may grade differently, so always strive to complete every step properly for maximum marks.
• 😀 Don’t rely on teacher leniency; do the work carefully and confidently to earn your marks.
• 😀 Practice by checking sample answer sheets to understand common mistakes and how to avoid them in your exams.

Q & A

What mistakes do students commonly make in board exams according to the script?

Students often make mistakes like using incorrect values, missing out on required steps, or not paying attention to the order of operations, especially in questions involving geometry or trigonometry. These errors can lead to marks being deducted.

What is the importance of writing all the steps in a math exam?

Writing all the steps ensures that students get marks for their process, even if the final answer is incorrect. Teachers might still award partial marks if the method is shown, but simply copying answers without work may lead to no marks.

How does the script explain the impact of incorrect values in exam answers?

Incorrect values, like in the trigonometric question where the student didn't use the correct value for 30 degrees, lead to completely incorrect answers. This can result in zero marks for that question, even if other parts were correct.

What is the significance of understanding and applying correct order in similarity questions?

In similarity questions, the order of the corresponding angles or sides is crucial. Incorrectly ordering them can result in losing marks even if the other calculations are correct.

What is the recommended approach to answering board exam questions?

The script emphasizes starting with a clear understanding of the question, using correct values and maintaining the right order. Mistakes should be avoided at the beginning, and students should confidently write all required steps for every problem.

How can students avoid the mistakes shown in the script, such as missing a critical value or order?

Students should ensure they memorize important values like trigonometric ratios and always double-check their order when writing solutions, especially in geometry or similarity questions.

What does the script suggest about the teacher's grading habits?

The script mentions that some teachers may deduct minimal marks, while others might take away full marks for errors. Students should aim to avoid mistakes to prevent heavy deductions and ensure they earn full marks for their work.

Why is it important for students to practice their work before the board exams?

Practicing by solving previous question papers and reviewing solutions helps students avoid common mistakes, builds their confidence, and improves their ability to apply concepts correctly during the actual exam.

What role does memorization play in board exams according to the script?

Memorization, especially of key values like trigonometric ratios, is crucial. Without memorization, students might make errors that could cost them marks, as in the case with the incorrect value used in the trigonometric question.

What does the speaker say about copying answers without showing the work in board exams?

The speaker advises against copying answers directly without showing the necessary steps. Even if the final answer is correct, failing to show the steps means students won't receive full marks as the method is not clear.
