From your question it is clear that you already completed your graduation degree. So, why are you going to do an integrated bed. Degree?
BEd degree is basically done by the students who wants to make their career in education line. So, if you have decided to take teaching as a career options then you must have a BEd degree.
BEd can be done in two way. One is after 3 years graduation you can take 2 years BEd degree. Here you have to spend 5 years time in total. Another is the integrated BEd which can be done after your higher secondary classes. Here you have to spent total 5 years of time. Here you get two separate certificate. One after your graduation and another is after completion of Bed degrees. Here you can save 1 year time.
But you have already done your graduation for 3 years. As per my opinion you should take 2 years BEd degree, because if you take integrated BEd now it will take 4 years which means wastage of 2 another year and there is no justification to do that because you already have a bachelor's degree. A 4 year integrated BEd is also wastage of money too.
Moreover in many examination and institutions they only allow 2 years full time BEd course for their educational criteria. So, as you now completed your graduation degree, there is no need to pursue a 4 years integrated BEd degree.
