My sugegstions are somelike similer to wht other members said. I would sugegst yout o keep in my that "Time never bound the one who has determination to do something" (My thought)
While studying one thing you keep in mind "I can do it" It is simple yet very very powerful thought.
Your attempt is in May'10 so you have lot of time though yo are self preparing. Why you are scared ??? No need to !! :) chill pill yaar !!!
Whenever you feel depressed then think of good moments of past like how you able to pass CPT or PCC so easily..(easy word is to motivate you :) )
Let me know if you are still unable to make your mindset towords study.
:) cheers the helping hand :)
