Calculating count of aggregate averages that meet a criteria

[JC_1]

Hi,

Apologies if this has been answered before as I am new to QlikSense. I am stuck with calculating a KPI that my company requires. 

Basically, I would like to find out the % of subjects taught across all institutions, taught on Campus that have a scoring of > 3.2 in a KPI chart.

So far, I am able to get the total number of distinct counts of subjects taught on campus across all institutions based on the following expression:

COUNT({<[Acad Year] = {"2019"}, [Location] = {"Campus"}>}Aggr(Aggr(Avg([Scoring]),[Subjects]),[Subjects]))

How do I calculate the distinct count of subjects meeting the above parameters AND have a scoring of > 3.2? That way I can use this to divide by the above expression to get my desired KPI value. 

Sample data set:

Acad Year	Institution	Subjects	Location	Scoring
2019	A	Math	Campus	3
2019	A	Biology	HBL	3.2
2019	A	Chemistry	Campus	3.4
2019	A	Physics	Campus	3.5
2019	B	Math	HBL	3.1
2019	B	Biology	Campus	3.2
2019	B	Chemistry	Campus	3.5
2019	B	Physics	HBL	3.7
2019	C	Math	HBL	3.3
2019	C	Biology	Campus	3.6
2019	C	Chemistry	HBL	3.8
2019	C	Physics	Campus	2.8

Taking into consideration only those taught on Campus:

Avg Math scoring = 3, Avg Chemistry scoring = 3.45, Avg Physics Scoring = 3.15, Avg Biology Scoring = 3.4

The result of % of subjects that score less than 3.2 would be 50% (result that I would like to get). 

Appreciate any help I can get!
