MISTAKES TO AVOID WHILE PREPARING FOR CLASS 12 PHYSICS?

Physics is considered to be the most difficult and complex subject by many of the students. This is due to the wide syllabus and problematic derivations. It is a tricky and complicated subject to crack. This subject demands conceptual understanding, visualization, logical understanding, practical knowledge, etc. mugging up things won’t work in this subject, you would require a deep understanding of the concepts. 

Students tend to make mistakes while preparing for this subject. Here is a list of mistakes that could hamper your performance and their solutions as well:

  1. No proper plan: the most common mistake which students do is that they do not have a proper and systematic study timetable. If they will give full attention from the very beginning, they will find the subject interesting and much more fun. You should design a proper study schedule. Allocate enough time for this subject. Your schedule must create a positive pressure on you, that will make you study more effectively and punctually,
  2. Not knowing the important topics of each chapter: students tend to neglect the important chapters and topics. Firstly check the whole syllabus and mark prime topics and key diagrams. here is a list of chapters and major topics which are to be given much focus:

CHAPTER 1: ELECTRIC CHARGES AND FIELD

  • Coulombs law
  • Gauss theorem and flux
  • Electric field by equatorial and dipole axial

CHAPTER 2: ELECTROSTATIC POTENTIAL AND CAPACITANCE

  • Alpha, beta, gamma decay
  • Nuclear fusion and fission

CHAPTER 14: SEMICONDUCTOR

  • Gates circuits
  • Devices [photocell, solar cell, rectifier, LED, Zenor diode ]
  • PN- diode forward, reverse

You must go through the above-mentioned topics by heart. Don’t leave or miss any topic. Pay more attention to these topics. Keep checking your syllabus, so that you don’t miss out on any topic.

  1. Buying a lot of books: you just need to stick to your school materials and Physics NCERT Books Class 12. Buy only one standard physics book. Instead of getting help from these books, you will end up getting confused and frustrated. study your one standard book thoroughly.
  2. Not making notes for each chapter: you should cultivate a habit of making notes while studying. You must recall concepts by just looking at them at a glance. These notes will be very helpful for you during the revision time. Keep writing key points and definitions separately. 
  3. Comparing yourself with others: never ever compare yourself with someone else. Everyone has a different way of studying, and not everyone learns at the same pace. All of us have our weak and strong areas. Students who like numerical problems should focus on the first part of the physics book. Students who are weak in the numerical part must finish with the theoretical part of the book first. Figure your weak and strong areas. You must focus on yourself and try to improve your performance day by day. Your biggest competition is you yourself.
  4. Not attempting sample papers before the final exam: the more you will practice sample papers the more will be the chances of you scoring high. You should at least give 7-8 practice papers in a time-bound manner to increase your pace. This will prepare you and your mind for the final and actual examination day.
  5. Neglecting self-evaluation: the best method to examine your preparation is by attempting various types of questions. After giving a sample paper, devote half an hour to one hour analyzing it. Go through the answers and Check where you have made mistakes or calculation errors. Try revising those concepts again to enhance your performance further. You must decide how much time to devote to every question and which section you should start attempting first. 
  6. No time for revision: in a subject like physics, revision plays a crucial role. Here, students have to deal with different equations, tons of formulas, complex derivations. So, it is better to keep on revising before moving forward. You should have formulas at your fingertips. Also, you must go through your syllabus at the time of a revision to ensure no topic is left.
  7. Not practising diagrams and derivations: you must solve each derivation 3-4 times so that it won’t consume your time during the exam. Practice diagrams twice and learn to label them to score good marks.
  8. Not taking proper breaks: students get frustrated as they study for a long stretch at a time. Instead, you must take proper breaks after every 70-80 minutes. This way your productivity will also increase and you will retain information better. Taking breaks will positively affect your mind and body.

Most of you might have found these mistakes very relatable. So, You must avoid these mistakes while you are preparing for your class 12 Physics. Staying away from these silly and easily avoidable mistakes will eventually enhance your marks, confidence and performance.
