Welcome to the Opentuition forums. For this particular question I would encourage you to ask the tutor directly as it is very specific. This forum is primarily designed for students to help one another. I would encourage you , however, to watch all of the lectures on site which are designed to be watched in conjunction with the notes available on this site. Also obtain a practice and revision kit from an approved publisher such as BPP or Kaplan. Find the ask the tutor forum for this subject here-
