The Fixed-Subject Block Method
The most battle-tested technique among serious JEE aspirants is deceptively simple: assign each subject a non-negotiable time window every single day, regardless of how the previous day went. Physics gets the morning block, typically 6 AM to 9 AM, because most students report sharper analytical thinking before the mental fatigue of the afternoon sets in. Chemistry follows after a short break. Mathematics claims the post-lunch slot, when procedural, repetitive problem-solving can carry you through the dip in alertness that hits around 2 PM.
