Physics Diagnostic Tests

The Physics Diagnostic Tests by PLS Academy are designed to help students assess their current level of preparation for entry tests, FSC exams, ECAT, NUST NET, and NTS exams. Covering key topics in mechanics, electricity, optics, thermodynamics, and modern physics, these tests allow students to identify strengths, weaknesses, and conceptual gaps. Detailed feedback after each test helps aspirants focus on high-yield topics, refine problem-solving skills, and plan targeted revision. Whether preparing for MDCAT, NUMS, ECAT, NUST NET, NTS, or FSC Physics, these diagnostic tests enable students to track progress, strengthen weak areas, and optimize their preparation strategy for maximum performance.
