11th Class Physics Online MCQs with pdf

11th Class Physics Online MCQs with pdf 11th Class Physics Quiz code. It includes 300+ unique questions based on the BISE Sahiwal Smart Syllabus (2025-26), specifically curated from the new National Curriculum textbook. Features Added: Subject: Physics 11th Class (New Book). Questions: 300+ real MCQs covering Measurements, Motion, Energy, Fluid Dynamics, Thermodynamics, Waves, Optics, Electricity, Magnetism, and Modern Physics. Smart Syllabus: Deleted topics (like basic scalar/vector definitions, simple elastic collisions in 2D) are omitted in favor of core concepts (Dimensions, Projectile Motion, Thermodynamics, etc.). Audio: Added a "Buzz" sound effect using the Web Audio API (no external files needed) when a wrong answer is clicked. Solved/Unsolved PDFs: Option to download the key or a blank paper. 11th Physics Quiz BISE Sahiwal (2025-26) :root { --primary: #283593; /* Indigo for Physics */ --secondary: #3F51B5; --accent: #FF5722;
