Filtering in Access

i need to know how to organize some data in access and filter on 2 criteria.

for example:

there are 100 people who need to be practicing 10 different excercises in a span of 2 hours. however there will be conflicts because 1 person will need to be in 2 places at 1 time. is there a way in access to filter the database to organize the most efficient and successful way to have people be in the most productive places?

thanks for any help,
