Create a 3 days study plan for me everyday has 3 study slots Morning afternoon and evening. My first annual exam which is held on 3/06/2026 so I want that give more time and revision session to those chapters which are imp. Organic Chemistry (Book) Here a chapter of organic chemistry Basic Chemistry (imp) Stereochemistry (imp) General preparation (Alkane,Alkene, Alkyne) (Past papers) Nucleophilic & electrophilic (Past papers) Orientation benzene Heterocyclic (imp) Reaction Mechanism (Most imp & Difficult) Intermediate & Free Radicals and Carbonium rearrangements & Carbanions rearrangements (most most imp). At the end create a image

A clean, colorful 3-day organic chemistry study plan poster for a student. The poster has a dark navy blue background with bright, readable text. Title at top: "Organic Chemistry — 3 Day Study Plan" with exam date "Exam: June 3, 2026" below it. Three columns for Day 1 (Saturday May 30), Day 2 (Sunday May 31), Day 3 (Monday June 1). Each column has 3 rows: Morning (sunrise icon, orange), Afternoon (sun icon, yellow), Evening (moon icon, purple). Day 1 Morning: Reaction Mechanism (Most Imp). Day 1 Afternoon: Basic Chemistry (Imp). Day 1 Evening: Stereochemistry (Imp). Day 2 Morning: Intermediates, Free Radicals & Rearrangements (Most Most Imp - highlighted in red). Day 2 Afternoon: Nucleophilic & Electrophilic (Past Papers). Day 2 Evening: Alkane, Alkene, Alkyne (Past Papers). Day 3 Morning: Orientation of Benzene. Day 3 Afternoon: Heterocyclic Chemistry (Imp). Day 3 Evening: FULL REVISION SESSION (star icon, gold). At the bottom a priority legend with colored dots: red = Most Most Imp, orange = Most Imp, yellow = Imp, green = Past Papers. Modern flat design, chemistry molecule graphics in corners.
Here's your visual study plan poster:
Key Tips for These 3 Days:

Reaction Mechanism + Rearrangements = 40% of your effort. These are the hardest and most important - never skip writing them out by hand.
Past paper chapters (Nucleophilic/Electrophilic, Alkane/Alkene/Alkyne) - don't just read, solve the actual past paper questions.
Stereochemistry - common mistake area. Practice R/S assignments until they're automatic.
Day 3 Full Revision is as important as Day 1 and 2 combined - don't exhaust yourself before it.
Sleep at least 7 hours each night. Memory consolidation happens during sleep, especially for mechanism-heavy material.
Good luck on June 3! You've got this. 💪
