General :: Divide Groups By Equal Distribution Of Merit / Talent?

I am with an educational organisation. Now we need to allocate various fields to students depending upon their merit, where the difference between the average percentages between any two groups cannot be more than 2% and that also implies equal distribution of talent. However, First few have to be given choice of field and also students recommended have to be given choice. The number of fields varies from 2 to 8. . Further the vacancies are also not equal in all fields. E.g. for 100 students to be divided in four fields the vacancies can be 35 for ZZSS, 24 for UYTE, 29 for OIUI and 12 for HGFT.

I need a solution preferably in MS Excel or MS access for the same with nil/ least usage of VBA.
