As the result of the research, it was found that there is significant difference between academic achievement and problem solving skills average points and class level and state anxiety average points It was determined that academic achievement and trait anxiety points predicted problem solving ability points. When t-test results about significance level of regression coefficient are examined, it is seen that the most important explanatory for problem solving skills is trait anxiety, then academic success.
