  paper was easy... but I made few careless mistakes.
  
  the SEQ quuestion... about detector for radiation. Dam... i thought Geiger Muller Tube was not possible based on the diagram of the thing. I put oscilloscope. Consider Correct?
  
  My 2 images of fishes was on the top of the fish tank.
  
  2nd question regarding the forces... unsure.
  
  the rest were ok...
  
  I think most likely overall for combine science B3 T.T

  anyone noe for this year's combine science... the most possible range of marks?
  
  A1 --> 80-100?
  A2---> 65-79?
  B3---> 55-64?
  
  b4? c5? c6?
  
  .... Everyone say combine science easy to score A. But i think due to my careless mistakes, I might fall to B3 T.T

  Because of easy paper, A1 standard most likely would be very high.

  2nd half life:160
  3rd half life:80.

  oscilloscope is for observing sound waves.
