Misconceptions in Physics
These videos describes the misconceptions a student has while solving numericals in physics and methods to overcome it
IBDP Past papers
The videos in this page shows the video solutions for all the problems (SL, HL) for both the time zones (TZ1, TZ2) for all past papers in physics for paper-1 ( MCQs)
Data analysis course for IBDP
The videos in this page leads to data analysis course offered in the IBDP Curriculum -2025 for Physics in paper-1.
Comparison Problems in Physics
Comparison Problems are Numericals in Physics, wherein a concept in the form of an equation will be applied for two sets of values for the variables given in the equation. The outcome needs to be determined by solving those equations either by simple division / algebraic methods.
Logical Reasoning Problems
Problems involving Logical Reasoning are common in Physics. Students make mistakes in such problems by not reasoning the concepts correctly. Such problems are discussed in the below videos.
One Problem a Day / HW Portal
Solving one problem daily can sharpen problem-solving skills, build a steady learning rhythm, and lead to a deeper understanding of each concept over time. It also allows room for focused analysis and critical reflection, making this a sustainable approach for long-term improvement.
Concept Wise questions for each unit
concept-wise questions helps you focus on one key idea at a time, making it easier to understand and remember. By practicing these questions, you’ll get a solid grasp of each concept, which makes solving complex problems simpler.
Teaching resources for all curriculum
Resources for students and teachers available for all curriculum and for all the classes
