@ ayudi
i appreciate your effort and dream to become an iit engineer from class 9 , thats a very good job .
see , in class 9th , u just need to be clear your foundation .
and that u can do by the following method
1- read ncert twice , and solve all the ncert problems
2- take out some etra ref books like s. chand , pradeep and dinesh publication books .
3- also u can opt for iit foundation package by askiitian and mtg publication also .
4- next attend the ntse , imo , nso, like olympiad which will help u to adjust with the competetive spirit of the student .
5- also do prepare for PSA , if thats avaliable this year , thats also a kind of good brain test .
6- NEXT , coming about h c verma , NO NEED TO START THAT FROM NOW ,
U HV TO START THAT AFTER U FINISH YOUR CLASS 10 , AND ON CLASS 1 1 STARTING .
so, dnt think beyond that , the books i hv told to you ,
and abt the sucess rate of coaching center , i think askiitian package is good , they also include the test series for class 9 , that have convenience , that u can attend that by sitting in home only .
AND IF U DNT HAVE INTERNET ACCESS THEN RESONANCE SUCESS RATE IS GOOD THAN FIITJEE .
LAST , BUT NOT THE LEAST , dnt stress upon yourself from now , u hv ample of time to get into an iit .
so, just refresh and relax yourself now .
ALL THE BEST FOR FUTURE .
