B.Sc

Hello Sujata,
Here you are confused about two different stream and field.
For B.Sc in nursing you need to complete 12th with PCB. This course is purely related with nursing and need deep knowledge of biology.
Another course you mentioned here is purely a management course so for this you does not need any knowledge of science.

Hello Venkat,
Definitely you can pursue B.Sc in Visual Communication. There is no age limit for that.You did a right thing by dropping Engineering, as you had 14 backlogs which would have created a serious problem in future and also it would have affected your other semester results and would have had a serious impact on your career as well. Visual Communication is a very good field and plenty of jobs are available for the same after graduation.
All the best.

Hello Mayank,
Since you have done your Bachelors degree in IT sector, MBA (IT) would be the better choice as there are plenty of job opportunities available in this field.
All the best!

You can pursue MBA or MA in English. You can also pursue a PG course related to B.Sc.

Scope in radio and OT are equally sound as there is a lot of scope in the future in radio and there is considerable need in OT at present.
Other than the scope, one should decide that in which branch one is comfortable with as its going to be a lifetime choice.

If you want to make a career in the science field, and if you have a dream of pursuing post-graduation from IIT's or IISC, then you can prepare for IIT entrance exams.
You can pursue M. Sc./Ph.D. & other post-graduate courses by clearing IIT-JAM entrance test.
