Index-Match-(or Vlookup) for Multiple criterias.

Hello Excel Gurus,

Would like to seek your help in getting a formula that will generate the corresponding rating attached to a row value and columns header as per below example:

EnglishSS1 EnglishSS2 EnglishSS3 Rating
10 20 30 3
20 30 40 2
30 40 50 1

Where my variables would be based on whether a person is under EnglishSS1 and getting a score of <=10, the resulting rating would be 3. I know this is doable by doing a vlookup with a range lookup value of false. However I have roughly 70 column headers and it will be a bit taxing to combine an If and Vlookup statement to address it.

I have attached a sample sheet for reference.

I thank you all very much in advance for your awesomeness!
