Good 'enough'? Enough can mean quantity, or it can mean quality. I.e.(only) one conversation will be enough to check my English, or "A conversation will be good enough to fix my mistakes."
Better to say, 'a general conversation would be good for me' and then you can say why. I.e. it would be good for me to 1) check my thinking and answering skills in English, or 2) to check my listening and vocabulary skills/ability.
