Remember, you must take IELTS also. Fashion programs also require portfolios. You must submit a portfolio of your work during application. Read all the details on the website.

If you have very good academic records and admission letter, Avansea education Loan will give you loan without any security. You can also apply for many other scholarships.

It is necessary to give entrance exams for MBA such as CAT, CET, CMAT, etc. in order to get a good college.

University of Chicago Booth School of Business
London Business School
Kingston University
These are some of the famous universities for part-time and evening MBA. Anything regarding fee and other financial things I would suggest you consult professionals.

There are many wonderful universities in London that you can choose. I am still willing to write an answer to this even after seeing the timeline when the question was posted. The reason is I have a friend who studied in the UK and was placed in a very good company. Do get good grades and get admission in one of the best universities in the UK.
