Hello,I Am Shiva Praneeth. I am going to attend for cpt exam very soon. But i am confused in the matter relating to the calc required for the cpt exam. I am confused whether the "Tax Function" is allowed or not & what does this 6 functions & 2 memories mean. I am eagerly waiting for an early reply. -Thank You.
