ECAT, NET and MDCAT Physics: Class 12 Topics (Bilal Zia)

The second half of Bilal Zia's entry-test physics series in Urdu, covering class 12 topics for ECAT, NUST NET and MDCAT. It begins with heat and thermodynamics (temperature, thermal expansion, gas laws, kinetic energy of gas molecules, the first and second laws), moves through electricity and magnetism, and ends with atomic physics (X-rays, lasers) and nuclear physics (radioactive decay, mass defect, binding energy). Lectures are long, problem-heavy sessions; the full playlist is close to 80 hours. Pair it with the class 11 part of the same series and with past papers for complete preparation.
