Mandana - Playing her game perfectly, she is consistent so far, has her opinion, use her mind and shows courage to stick with what she believes.
Kishwar - Brat image, consistent, using her mind, dominating her group, has her opinion. Very much like Mandana but with India khoon.
Aman - Consistent, using brain, read the situation nicely, one man army
Keith - He is doing OK, he has more negative than positive. He is portraying himself as nice person and good listener, but get influenced easily, does not have his opinion.
Prince - Positive: maintaining his flirt image, negative - does not have his opinion at all, he not a leader but follower
Yuvika - She is playing OK, she trying to maintain her goody good image and successful so far without being noticed
Rochelle - She is too much cautious of her image, it clearly shows she is trying her best to look good, does not have her opinion.
Vikas - Tough to point out any positive, so far looks like a person with no base.
Rimi - Funny, but she wants to go
Rest - Fillers, show needs few people for weekly eliminations.
In my opinion: Top 3 BB materials are Mandy, Kishwar and Aman
