Strategies for Navigating Hard and Unusual Class 12th Physics Exams

Preparing for the Class 12th Physics board exams, especially those governed by the CBSE, can be challenging. When the exam paper is unusually difficult or out of the usual pattern, students often find themselves unprepared. Despite being thoroughly revised for frequently asked topics, potential shock and pressure can leave students feeling unsupported. This article provides insights and strategies for handling such unforeseen complications.

Dealing with Unexpected Question Papers

During the 2018 CBSE Class 12th Physics board exams, many students faced a paper that seemed out of the ordinary. Despite having an average knowledge base and reciting frequently asked concepts, the exam posed unexpected challenges. Here are some key strategies to follow:

Stay Calm and Confident

The first step is to take a deep breath and avoid panicking. It is crucial to maintain confidence and stay composed. Begin by attempting to answer the questions you are certain you know. This will help build your confidence and also ensure that you secure points where you may have otherwise faltered.

Identify and Break Down Unknown Questions

If a question is complex or unfamiliar, identify parts of the question that you can confidently answer. For instance, if a numerical problem arises that involves Electromagnetic Force (EMF), start by defining what EMF is, its unit, and other related concepts. Continue to break down the problem as far as you can. This approach can help you gain partial marks, which can be crucial.

Commonly Repeated Topics and Key Concepts

For the 2018 CBSE Class 12th Physics exam, there were several key topics that recurred with high frequency. Mastering these topics can significantly improve your performance. Here is a comprehensive list of these important topics:

Important Topics and Repeated Questions

All Derivations Solving a system of charges using the Vector method Electric field of a dipole Torque on a dipole Kirchhoff's laws and solving circuits Capacitance and solving circuits Potential of a dipole Ampere's circuital law Biot-Savart's law Lorentz Force Faraday's Law and Eddy currents Mutual and self-inductance LCR circuits (RLCRCLC basics) AC generator and transformer Uses and production of electromagnetic waves Lens makers' formula Internal total reflection and its applications Combination of lenses Diagrams of microscopes and telescopes, resolving power Young's double-slit experiment (YDSE) Diffraction Polarization Brewster's Law Einstein's photoelectric equation (including graphs) An atomic experiment Energy and momentum in a nucleus Potential energy and energy per nucleon curve Types of radiation and nuclear energy Energy band theory Diodes - PN, Photodiode, LED, Zener, Solar cell, and their IV characteristics Transistor - Characteristics or Amplifier Digital electronics - Solving logic circuits and truth tables Basics of communication systems - Attenuation, Noise, and Transducer Amplitude Modulation (AM) transmitter, receiver, and amplifier with block diagrams Need for modulation

Sheer practice is the key. Solve all the numericals and previous year's papers to ensure a thorough understanding of the topics. This practice will not only enhance your problem-solving skills but will also familiarize you with the types of questions that can be asked.

Conclusion: All the Best!

A thorough revision of these key topics and consistent practice can significantly boost your chances of success in the 12th physics board exams. Remember, confidence and strategic preparation are your best weapons.
