Jaipuria Lucknow - Jaipuria Institute of Management

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.

The level of difficulty is unpredictable as it varies. However, I'll say moderate to tough. But if you know about the distribution and percent weightage of marks in the admission process at Jaipuria Institute of Management, you may prepare more efficiently for admission. They are as follows:
1. Score 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%. If you combine the percent scores allotted to GD and PI, it sums to 35%, and hence it becomes important to prepare for both.
92 percentile in MAT is fine but like I said, these scores contribute to 45% weightage in the selection process. If you do well in GD and PI, you may qualify for the admission. Wish you all the best.
