hi,

see Principles of Physics by Halliday Resnick Walker or University Physics with Modern Physics by Sears and Zemansky  are mainly referred for jee main and advance preparation, so basically this books are for better concept building. first to read from your text 10+2 course books, then once your board syllabus is covered you may try for this books for generalized concept. now it depends on the quality of students and how much time she/ he may devote for extra lessons. generally It would take around  6-8 month year to fully complete these books.
