Best Cost And FM teacher for ipcc for May 2015

Hi guys,

Can u suggest me who is the best teacher for Cost and FM in Kolkata

1. Ankit Patwari ( Awesome teaching method but not included in package so bit costly. 3 centres: Girish Park, Hazra, Southern Avenue)

2. Manish Raj Dhandaria (Teaching so so and forms part of package so can avail discount 1 centre: College Street)

3. Vivek Soni (reputed teacher 1 centre Theatre Road)

4. Alok Chakraborty ( Too much detailed..not required for IPCC and centre location is also not dat gud 1 centre: Lake Garden)
