Colleges in Ranchi

If you want to apply for government jobs or competitive exams, for most of the competitive exams, you need to have a graduate degree. You should complete your graduation from a reputed college.
Candidates who have done Diploma, they are not eligible.
Firstly, you should check the eligibility criteria for every exam.
So if you have a graduation degree, then you can apply for many exams such as IBPS bank exam, railway exam, UPSC exam, SSC exam, etc.

Almost around 70-80% for general category.

SP Jain is a better choice.

Dear Sinha,
Before you enter any B-school, you should check the current placements. BIT - Mesra is doing well but check once again with the seniors.
All the best.

BIT Mesra CSE department is ranked 20 in All India ranking. It is a better option among your choices.

Certainly, it is not recommended. I have not even heard a brand and does not carry any great career prospects. You can look for top 30 MBA colleges only, else it is not worth doing MBA.

All 3 are the best colleges & among top MBA colleges.
if you select any one your future career will be safe.
As per my knowledge it is 90 percentile for CAT, it may change for CAT 2016 as per IIM, Ranchi decision.

IIM Ranchi is in top 50 B-Schools of India and is very good MBA option. It's all India ranking as per Business Today and Week 2015 is 38 and 26 respectively.
