looking up data in a table that has duplicates with different values that are both being reported

[Zhemann]

I have a spreadsheet with classes that fulfill certain requirements and all of the classes are listed in a column with their requirements beside them, however their are duplicates as some classes fulfill 2 requirements. I have a table on a separate sheet that has the classes with the duplicates removed that is supposed to be for recording what they fulfill using an IF function for filling in the cells. The classes are on the columns and the different categories they fulfill are on the top across. I was using a VLOOKUP function but It only records the first requirement for the class and reports false for the the next. I'm pretty sure an INDEX MATCH function would work but I'm not sure how to do it. I can't seem to figure out how to have it search the whole column without stopping at the class and only reporting it's first fulfillment.
