I have an Excel spreadsheet with the following data:

#-----------------------------------------------------------------------------------------------------------------------------------#
#    Student    #   KS2 Grade   #  Target   #   Expected 1  #   Expected 2  #   Expected 3  #   FSM Status  #   Gifted & Talented   #
#-----------------------------------------------------------------------------------------------------------------------------------#
#     User 1    #       4       #     6     #        7      #       5       #       6       #       Y       #           N           #
#     User 2    #       3       #     5     #        5      #       4       #       4       #       N       #           N           #
#     User 3    #       5       #     6     #        6      #       6       #       7       #       N       #           N           #
#     User 4    #       4       #     6     #        5      #       6       #       6       #       N       #           Y           #
#     User 5    #       5       #     7     #        7      #       6       #       7       #       N       #           N           #
#     User 6    #       3       #     4     #        4      #       4       #       4       #       N       #           N           #
#     User 7    #       3       #     4     #        5      #       3       #       4       #       Y       #           Y           #
#-----------------------------------------------------------------------------------------------------------------------------------#

What I'd like to do is determine the percentage of students with certain levels, i.e. a range of levels.

For instance, in the data above, I'd like to determine the % of all students that have a Target level of 5 - 7.

I'd then like to also expand the formula to specify % of Gifted & Talented students with a Target level of 5 - 7.

Is this possible in Excel? If so, where do I start?
