Hello

We are a bit late in replying to you but we hope this reaches you in time.
The segment on career goals is the most important part of any Master’s application and it is great that you have identified your problem and are seeking a solution for the same.
The key to delivering a good application is one that shows a direct sync among you short term goals, your long term career plans, and how the degree in question will facilitate your journey towards your goals.
Further, while an MSc in Marketing would have provided you subject matter expertise in Marketing, an MBA will provide you a 360 degrees view of looking at business, instill in you greater soft skills, and afford you a recruiting advantage.
Besides elaborating on the above-mentioned points, we also recommend that you evaluate your existing skill-set and think about the areas you could improve upon. In doing so, you will certainly have your answer

Hope this helps.
All the best!
