@GSK Trick, if we can call it that, is
1. Apply from as many Acs as possible (different PANs)
2. In mainboard apply lowest in the category
a) retail 1 lot
b) SHNI generally 14 lots
c) BHNI henerally 67 lots.
3. In SME IPO apply as higher number of lots as possible.
4. And most important never loose hope..
All the best..
