First of all, learn all concepts from NCERT/ICSE books. Practice all problems (model wise) from units 1, 2, 5, 5, 7, 8, 15, 16, 17, 18. Practice all name based reactions in alphabetical manner ( ex: acylation, alkylation, aldol, benzoylation, Canizzaro, so on….,) and all interconversions as appear in intents, exercises, learn basic reagents, importance, limitations, stereochemical aspects where ever applicable (ex:SN1 of optically active haloalkane, nucleophillic additionof aldehydes, mixed ketones, addition of bromine across C=C in cis and trans isomers).
Compare groups from 1 to 18, d block, f block. Especially oxidation states, halide, oxides, nature of oxides. Also try to write flow charts.
Hope, information is useful….
After near perfection, try to practice MCQ from old AIPMT, NEET, IITJEE MAIN, CET (OF DIFFERENT STATES)
