JEE tips

Revise Purification: Crystallization, sublimation, distillation, differential extraction and chromatography principles and their applications with a one-page formula sheet before attempting mixed tests
After each practice set, log mistakes specific to Purification: Crystallization, sublimation, distillation, differential extraction and chromatography principles and their applications and reattempt after 48 hours
Revise Qualitative analysis: Detection of nitrogen, sulphur, phosphorus and halogens with a one-page formula sheet before attempting mixed tests
After each practice set, log mistakes specific to Qualitative analysis: Detection of nitrogen, sulphur, phosphorus and halogens and reattempt after 48 hours

Common trap

Students often rush Purification: Crystallization, sublimation, distillation, differential extraction and chromatography principles and their applications questions without checking units, sign conventions, or boundary conditions — always verify assumptions before calculating.
