Need to always check for Q?

In some problems in the homework (like 5I.25 7th edition), the initial amounts of the mixture include both products and reactants. Therefore, the solution manual did a check for Q first to see if the reaction will move forward or backward. Do we have to do this too each time there are both products and reactants added initially, or can we just assume the reaction will move forward unless otherwise specified? The other problems in the homework didn't seem to check for Q first.

Just to be safe and check your work you should check to see which way the reaction will move if possible.

I agree you should just check for Q just to be on the safe side.
