Dual

In my view Marketing-Logistics is better option. As there are many manufacturing companies who recruits MBA students for sales, and if they get people with dual experience of marketing and logistics than operations management along with sales management will be assets for them.

Sir,
There are very few chances of getting a seat in the AU or in its affiliated colleges.
Please participate in the counselling conducted by AU from June 4th onwards.

B.Tech is better.

Previous year's questions are usually available in college or on their webpage. If you can't get them, try asking your seniors for them.
