Take youtube classes of " Dani ki Costing " all other teachers are crap , classes are available free of cost and search on google " Dani ki costing notes "
As of isca, you may go for Swapnil Patni sir.. u may even buy video lectures and watch them as per your comfort, say while travelling etc ( Mind the security and view system though ) But instead of rushing, plz do watch demo lectures on YouTube as not all teachers may suit all students! :)
no other option for isca...as I said to earlier..baat maan...Swapnil sir iz best..m sure u will definitely like him n able to get confidence over the subject as well as score high.
sanjay sir having much more cleat concepts and Parag sir having exam point of view explanations..choice iz urs...but overall sanjay sir iz gud
I know satellite hoti hai...bindaas ja...tujhe sir se pyar ho jaega...trust me.bas jaisa sir bole waise hi padhio.stay blessed...I hope now Ur querry has been resolved so now its action time.
dude go with dani ki costing one of the best teachers , with sanjay agg or parag gupta u will go mad , they take around 3 hrs of class every day with questions nd questions but dani ki costing classes available on youtube try standard costing first on my advice and after 35 videos decide whether to move with dani sir or not.
