Today I've received my toefl iBT test results. I scored 104/120
30 in the reading and listening sections
23 in the speaking section
21 in the writing section
although I met the overall score requirement for the university I wish to apply for, I need a minimum of 24 in the writing section, I need to know what are my chances of raising my score to 24 if I apply for a rescore. I know I did well in the first question (i expected a 5 or at least a 4 but i got 2.5-3.5 ~fair level~), I didn't do well in the second one (also got a 2.5-3.5 ~fair level~) if I apply for a rescore and got a 4 or 5 in the first question will it raise my score to 24 given that my score in the second question remains the same? or should I retake the test again?
Really appreciate your help.
