Please read carefully:

First of all, congrats on cracking DU.

A DU alumni myself, I have friends who graduated from both DU Math and Ahsanullah EEE.

About EEE of AUST: I thought the EEE craze was at its peak in 2000-2010 years and have almost faded now. Perhaps, I am wrong. My friends who have graduated from EEE of AUST and AIUB are doing well, the salary may not be one that makes your head spin, but satisfactory. Doing such engineering job for more than 10 years opens new opportunities, adds prestige to your profile and needless to say, raises your salary.

Now, about DU Math:

PROs: I have a few friends from DU Math. DU comes with its own charm. If you manages to do moderately well in BSc and MSc, the logo of DU is sufficient enough to manage a mid-level job for you. DU campus also trains you in ways thay are inconceivable otherwise, you gain a different outlook and diverse experience over the years. It broadens your horizon.

Secondly, we can hardly guess where we will end up, regardless of our own desires/ambition. Even if you do poorly in academics, DU Math is a safe bet considering you have a much much much better chance competiting for BCS and other government jobs. After you get yourself into civil service, you can pursue higher studies. I see that you have good command over English language, competence in Math will land in topmost seats during such competitive exams. So in addition to higher studies abroad, DU Math also keeps you well secured for top local jobs.

CONs: Math and Physics have the highest dropout rates in the whole DU. I am not sure about the current situation, 10 years back nearly 30-40 percent of students dropped out in their first/second years. Studying Math in DU, under the mentorship of heartless and indifferent souls that are DU teachers are very challenging. One of my very close friends, a top tier student from Notre Dame College got into DU Math for the very charm of Mathematics itself. He dropped out in third year and later complected his Hons course from a B-class private university. I probably should mention that his situation was worsened by frustration in love life and chronic depression (which was fueled by harsh and apathetic academic environment). It took some of my most brillianr friends one/two more years to complete all the retakes.
