hi , need advice on income tax and group 2

im pursuing the old scheme of education that is the pe2 exam ,and for the recent may 2008 attempt which was my 3rd attempt , i cleared my 1st group , but i really did expect to clear my 2nd group also , because i thought that no matter even if marks may be a little lesser for the other 2 subjects , after writing the tax exam i felt i had reallly done it well and would score likewise , but it really shocked me when tax turned out to be the only paper i failed .( i really worked hard for tax too , have presently given for rechecking) ). i have however decided to give it another try . i am getting a little frustrated sitting at home since one year is over after college finished . can u please give me the advice i need on how to approach the 2nd group especially income tax , and about my present situation ? i really feel i must finally clear the next attempt for good .
