I have done 2 year coaching for iit from aacharya in nirman vihar. But I was not be able to get good rank .Please tell me what should I do .take 1 year coaching in resonance in mayur vihar but it is far from my house as I live in vasundhara or take 1 year coaching in prayaas academy in vasundhara sector13 as its close to myhouse. What should I do?

@ preeti 
take that in resonance , beacuse the other academy was not a popular one , and here u will face problem like suppose in resonance , u are giving the all india test sries , and u will get the rank among all the students but in other academy , u will not get that , and there also check the faculty profile . 
the faculty profile will matter much than test series . 
also , remember – every resonance is not good , so, judge that with  your full potetial . 
and also , check your comfort , u need time for self study also , beacuse that is very very important . 

i think its better for you to take askiitian live classes , they have iitian simmilar with resonance , and here u will get the recording of class , but their u will not . 
and also here the teaching will be at your comfort zone , but their u need to travel . 

also askiitian test series will be very better than reso . 
AND 1 MORE THING – IF U HAVE ENOUGH CONFIDENCE THEN ONLY GO FOR DROP , ITS ALREADY 2 MONTH PASSED NEARLY . 
U HAVE LESS TIME FOR JEE , SO, UTILISE THAT . 

ALL THE BEST ..
