is there a rule specifing how many romex can pass throw the same hole in a wooden joice?i can't find it, and also has anyone recently written the test,is it hard,any advice,do you remember any questions??

The rule is 4-004 (10)
If the total number of current-carrying wires in the same hole exceeds three, the correction factors in Table 5C must be applied.

What exam are you referring to? If you mean the Interprovincial, I used to teach apprentices who were preparing for it, before I retired.
