Piano exam - Grade 7. Trouble with aural (cadences)!?
I dont get what you mean by V, I (perfect) and I, V and IV, V (inperfect). how can you tell if it's perfect, inperfect and interrupt?
and if possible, please state examples. thanks

I am just going to add a bit to the above, for your ears sake. A perfect6 cadence is like a period at the end of a sentence, there is no feeling of a need to continue. An imperfect is like a comma, where there is a pause but the thought continues, an interrupted or deceptive cadence is like saying, "or" or "but", where something like before but a different aspect is expected and the pause reached does not give a sense of rest but rather feeling needing to move into a slightly different flow.
Cadences are a factor of voice leading. A perfect cadence is when the soprano voice goes from "ti" or "re" to "do" and the bass voice goes from "sol" to "do". Typically it is done in contrary motion (meaning the bass would go down to "do" if the soprano is going from "ti" to "do". Or, more rarely, if the soprano is going from "re" to "do", the bass voice would go up to "do" from "sol". All of this is happening while a V (or dominant) chord is resolving to a I (tonic) chord. Imperfect cadence is any other candence that doesn't follow the above rules. Composers use cadences to represent a sense of completion after a phrase. If it doesn't feel "right", it is probably not a perfect cadence. Some additional examples can be found at http://en.wikipedia.org/wiki/Imperfect_cadence
What country are you in? I ask because the meaning of these terms is not consistent throughout the English-speaking world.
