Jehad_b,
You are either in Jeddah or Riyadh, if in Jeddah then insist that your instructor explains the process to you correctly, if at the end of the lesson you still don't understand, then go to your fleet manager and complain. Remember that if you fail the course, its your fault and not the instructors and at that stage it will be too late to complain.
The procedure is extremely similar to the MD90.
