◆ calculatePoints()

static ilPageQuestionProcessor::calculatePoints (   $a_type,
  $a_id,
  $a_choice 
)
static

Calculate points.

This function calculates the points for a given answer. Better would be to re-use from T&A here in the future. When this code has been written this has not been possible yet.

Parameters
