Improvisation Is The Future

OK well I'm back in school tomorrow, which is neither good or bad. Now my plan was to record a song during my music lesson for my GCSE the way I shall do that is by making up a riff/chord pattern now and tomorrow I'll make up the lyrics as I go along. This could be fun, especially since I'll put that forward to my teacher using it to get my music GCSE, I can't wait.
