Colleges in Lucknow

If anyone has CMAT percentile between 95 and 100, he/she can apply for Jaipuria Institute of Management. Remember the CMAT/MAT/XAT/CAT score contribute to 45% weightage only during admission process, other factors like your GD, PI, past experience, and your academic performance contribute to 65%. So, prepare well for the personal interview and group discussion also. Let me share the weightage of scores during admission process, it will clear the doubts from the first part of the question:
Score in CAT/ MAT/ XAT/ CMAT/ GMAT 45% weightage
Case-based Group Discussion - 15%
Personal Interview - 20%
Academic Performance - 15%
Work Experience, Sports and Extracurricular Activities - 5%
If you do well in others too, with such decent score in CMAT you might be eligible for good scholarship as well. Now, regarding the second part of the question. The ministry of Human resource has place both Principal L N Welingkar Institute of Management Development and Research and Jaipuria Institute of Management in the top 75 b-schools of India. So, both are good. However the choice is yours. You can do analysis, gather placement data, most importantly it depends on where you live. I hope you know that Mumbai is the most expensive city to live in India. My preference would be Jaipuria Institute of Management - Lucknow.

The preference should be made on where you live. Since, all four campuses belong to the same brand, most things are same, even placements are centralized. So, if you live in Lucknow, then choosing Lucknow campus would be wise, as you'll save the hostel fees. There is a difference in the fees depending upon the campus too. PGDM is offered in all four campuses. However, PGDM - Financial Serves amd Retail Management are offered in Lucknow only, PGDM in Service management in Noida and Jaipur, PGDM - Marketing in Noida, and PGDM in all four. So, if you're stream specific from graduation, then you can choose accordingly, otherwise all are good.

If you are asking about PDM/MBA, then the top 2 institutes in Lucknow are IIM-Lucknow, and Jaipuria Institute of Management Lucknow. If you wish to pursue your PG from Lucknow, try to do your best in CAT and get enrolled in either of the two. Don't fall for other institutes, most are fake. I belong to Lucknow and I know most of them. Except these two (IIM-L and Jaipuria), if you go to any other b-school in Lucknow, they will give you admission right away, maybe they'll give you discounts to win your trust. Sadly, most people are fooled by these fake colleges. And after two years, the students realize that they're not ready for the corporate world, no personality development, and the last nail on the coffin is fake placements. God save the world. Anyways, you asked for top two. As per my knowledge and experience, there are only two institutes you can trust, first, obviously, IIM-Lucknow. And second is Jaipuria Institute of Management Lucknow. I don't think that I need to say anything about IIM-Lucknow, everyone knows they are the best. Regarding Jaipuria Institute of management, I've been there. I've seen the environment. They are doing good for the last 25 years or so. The faculty highly qualified and really helpful, too many curricular and extra curricular activities, personality transformation and good placements. In fact they let their students appear for placements in all four campuses (Lucknow, Noida, Jaipur, and Indore). I know its really hard to get in an IIM. If youget through, great. Otherwise go for Jaipuria Institute.

Yes, it is mandatory to appear in CAT or MAT or XAT or CMAT, etc in order to get admission in Jaipuria Institute of Management. This percentile score contributes to 45% weightage during admission process.
The admission procedure comprises of following factors:
1. Score in in CAT/ MAT/ XAT/ CMAT/ GMAT : 45% (maximum Weightage)
2. Case-based Group Discussion : 15%
3. Personal Interview: 20%
4. Academic Performance (previous): 15%
5. Work Experience, Sports and Extracurricular Activities: 5%.
So, if you do well in entrance exam, GD and PI, you'll have control over 45+15+20 = 80% weightage during admissions. And obviously, you'll get some marks in Academic performance (15% weightage). Now, the 5th category weighs 5% only.
To know the exact percentage of students placed, you may have to contact them. But their placement record is good. Companies like Hindustan Unilever, HDFC, Amul, etc come here.
