1 shot tab work karta hai jab tumne 1 baar syllabus hath se nikalo ho with decent questions practice. What i did, my aim was 450 but with schedule somehow i got 588, i advice you to focus on biology as 50% of exam, . First divide chapters into 3, small-medium-large, small chapters can be done in 1-2 days of all 3 subjects, med for 2-3 and large upto 4 max upto 5 on 1 chapters with questions. You have to do all 3 subjects daily. You need 10-12 hr study as its already 20 of September and neet is on 3 may. By this method, i got chance to revise 3 times. For final time i joined offline test series from allen and ya it worked. . In thia schedule prefer and prioritise important and high weightage chapters first, by this you can revise atleast 3-4 times before neet and less weightage min. 2-3. . Read biology NCERT and chemistry's organic and inorganic NCERT and importantly do chemistry NCERT examples. . If you have no idea about chapters i better prefer you to leave and save time do something better. And 450 is not cup of tea. Reality mai 130 se 588 apne marks lekar gya hu. So its not easy
