For the case of an international student..
How much does GMAT outweigh undergraduate university marks?
For example, I graduated in Actuarial Science (which is quite harder than other Bachelor of Business Science degrees here in South Africa, probability of gruaduation in 4 straight years is less than 50%). Now, some top universities require at least 70% aggregate which I just missed by inches. However, I'm almost sure that I could have made it well over 70%,if not a first class honours, if I had taken another business science degree.
Now, the best I can do now to prove myself is to do well in GMAT. I took my first GMAT last week and got a 620. However, I was not well prepared (spent about solid 5-6hrs preparing, I didn't know how much was required). Now I'm going to prepare (4-5 months perhaps) for a 720+.
I want to get into a good university either in USA or in Europe. My current aim is not an MBA but a MSc in Management or one of a similar nature.
What are my chances into top elite, elite, near elite universities? Any opinions or suggestions? Especially optimistic views will be appreciated. Thanks
