Ms Indri - ICT team teacher of JPS - gave me a CD ROM."Sir, this CD own a students. This is can not open. Please handle," Ms Indri said yesterday. "Oh, may be the CD -that they bought in last Saturday, October 1, 2011  when Optima staff sale. The Optima staff  sale when JPS  Open  House, October 1, 2011. I  forgot to check it yesterday. I want to check it know. "If it error, I will  email   it to Optima but if still good, I will  say to the students and parents. I put it on CD ROM  of laptop. It's  run  while exit music. Ms Indri  want to teach YHS 9. She feel disturb with music of  CD. She reprimand me:"Sir, SIR, PLEASE SMALLER VOLUME OF MUSIC ON LAPTOP," . I try to do it. It's need  time to stop. The laptop difference with speaker that have button to move volume. I get the trick to off it is press simultaneous button on keyboard: Ctrl - Alt - Del - than select End - . The student see   complain  too. I do it. The students  make  presentation about Link of internet. I busy to looking  for material. I read it. I find  it. What i do is mistake but not right time. Please improve yourself, Franck.
