B.Sc Chemistry

You can do MBA but I suggest that you choose your specialization subject based either on the type of job your are doing or the one you want to do or on the basis of your graduation subject. If you did it in chemistry then one of the options is to do MBA with specialization in Operations. You can even choose Marketing for that matter. But Santosh make sure that it is related to the kind of work you are looking forward in your career.

Both offer job opportunities but the field is different in both. So, go in the field you are interested in.

Going for msc (chemistry) is a decent choice. She may also pursue any applied chem or bio subjects like industrial chem, analytical chem, biochem, biotech etc. After msc, she can clear ugc-net to pursue phd and compete assistant professor exams. All the best. Thank you.

Hi Jishnu, you need to research on the universities in NZ, check the websites and understand the admission requirements. You need to meet the criteria in order to be eligible to apply. New Zealand universities seeks high academic grades, in addition you must take IELTS and any exam which may be required by a particular university. University of Auckland, University of Canterbury, University of Wollongong are good options.
