Hi, I did Persian last year. I know that Persian is a rare subject, which means that there is limited resources for it. But in order to succeed in it, it is highly recommended to make good use of the past exam papers and examiner's reports in vcaa website. It is better to time urself when doing those past exams, so that u will know how long it should take you for each section, in the actual exam. Besides that, try participating in class diacussions very frequently in order to enhance your speaking skills. It is very vital to be able to communicate well with the examiners in the oral exam. I remember a teacher told me to speak to the examiners so much that they become fully annoyed! So make sure you dont only answer "yes" or "no" to their questions.
Hope you be "moafaq"(successful) with Persian and all other subjects.
