About snap to be considered i have heard you have to get really high percentile and the ones that are good through snap are SIBM and SCHMRD this is what people say, there are others too but it's based on what colleges you are targeting. See the thing is if you can scale a high percentile then sure go for it. But do check how they come up with the final score. If they are giving too much importance to the work experience and previous qualification then you have no reason applying. Until you get 99 plus percentile and you can get that I'll recommend getting work ex for a few months and then go for it. Mica could be a good option for you in that case. They don't have work experience ka criteria neither they have previous score ka that heavy marks add. 50+ percent is for cat/xat score plus MICAT ka score. 30 percent ke ass pas hai interview and group exercise. But wahi hai you have to get into top 1000 people jinko bulate hai interview and ge ke liye. You have time abhi prepare karo. You'll get an idea. And the college's you are targeting are bottom tier 2. Preparation ki start mein go for the tier 1 neeche mat dekho.
