Dear Applicant,

I hope you are doing well, about your question, both the course are good enough be it integrated or regular mode. The only difference  between the 2 is the time taken for completion your MSC in regular mode will be for 2 years only

Now if you choose integrated MSC in maths with b.ed you are eligible to get a job for teaching basis till hss level is. 12class. Very rare tr with bed get jobs as assistant Professor in college and if you do that's on temporary basis not fixed.

Now if you persuade a masters degree from regular mode it has a slight more advantage and preferences as after MSC you can try for csir NET exam and if you qualify that you can teach at UG level or even try for PhD. This is the greatest advantage of regular mode it has quite abit of flexibility. That allows you to move freely.

Hope this helps
