To prepare properly for any examination you need to make a proper and programmatic study schedule or routine. Then go through the entire syllabus. Instead of choosing a random topic from the syllabus, you must break your preparation into sections. Sub-topics from each section should be selected and then strategy on clearing concepts must be made. You can make short notes on the topics that you have find difficult to understand.
Never leave any concepts doubtful or unsolved. Once done with the syllabus and concept clarity, you should move towards solving previous years papers. Give mock tests as much as possible. Time management is one more important thing you should look upon. Remember that practise will increase your efficiency.
Give at least two mock tests every week. Then analyze your weak parts and work on them. If you find it difficult to prepare from books like HC Verma, DC Pandey, then only go for NCERTs. From wherever you study, you must complete NCERT Textbooks as many questions are directly asked from NCERTs.
Some important chapters you must focus on- For Physics, Rotational Motion, Thermodynamics, SHM, Electrostatics, Magnetism, Optics, Modern Physics. In Mathematics, Complex Number, Conic Section, Circle, Calculus, Vector & 3 D, Probability, Trigonometric Equation, Properties of Triangles, Quadratic Equation, Sequence and Series, Permutations and combination. In Chemistry, you can more focus on these chapters for last month preparation- Chemical bonding, Electrochemistry, Coordination compound, Salt analysis, Ionic equilibrium, Thermodynamics & thermochemistry, Aldehydes and ketones, Aromatic hydrocarbons, GOC isomerism, Liquid solutions, Alkyl halides and aryl halides. Beside this, give mock tests regularly.
