Step:1–Categories Topics as per your Prep Level
Physics- Prepare key points of all chapters, Categorising them in three groups as per your command level, and then attempt questions from previous years.
Chemistry- Pay special Emphasis on chapters which including Atomic structure, Solid State, Ionic Equilibrium, Electrochemistry, Thermochemistry, keep jotting down simple formulas that you encounter while solving questions, these would come handy while practicing in the final week.
Mathematics- Start with the basics of differentiation and work your way with limits and associated concepts. work hard on properties of definate integrations and revise differential equations.
Step-2–Analyse work areas and work on them
Physics- Go through books/notes for areas with a poor command to understand key concepts, Practice more from standard sources, and then attempt questions from previous years.
Chemistry- Focus on various name reactions that you have studied across XI & XII and their mechanisms, practice questions related to ozonolysis, aidol & cannizzaro reactions, Which is frequently asked in JEE Main Exams, questions related to acidity and basicity order should be practiced thoroughly along with chemical tests for various functional groups.
Mathematics- Start your week with revision of formulas and keep a keen eye on similarities between them and work on geometrical properties of Conics keeping in mind their applications.
Step-3–Revise the topics that you are good at
Physics- Practice topics where you have a good command also pay attention to topics that are there in JEE Main Exams but not in JEE Advanced
Inorganic Chemistry- Focus on topics including Chemical Bonding, p-block elements, coordination chemistry and qualitative analysis.
Mathematics(Algebra)- Start with Quadratic Equation and work your way towards complex numbers, Focus on the properties of matrices determinants and also vectors and 3D geometry, keep a more problem based approach towards permutation and combinations, probability, progression and revise formulas.
Step-4–Attempt mock tests and analyse
Physics- Practice one test everyday followed by in depth analysis on the basis of mistakes you committed and the overall speed of solving questions, Ensure that you attempt the test assigning the same duration of time that of JEE Main 2020.
Chemistry- Now that your entire revision is complete, spend time revising the notes you made daily for the past three weeks and take mock test daily along with doing their detailed analysis.
Mathematics(Trignometry and general revision)- Start your revision with trignometry identities and inverse trignometry work your way towards the solution of triangles and keep a firm grasp over formulas.
