That was much lower than anticipated by the National Institute of Education Testing Service (NIETS), which estimated that 2,000 students, or about 300 each day, would want to see their Ordinary National Educational Test results, director Uthumphorn Jamornman said yesterday.

The NIETS allows students who thought they did better than their published scores to recheck their answer sheets from yesterday to April 30, excluding the Songkran holidays. They are charged Bt20 for each of the five subjects tested - Thai, social science, English, maths and science.

The first session for rechecking will open on April 23 and students will have 30 minutes each to examine photo files taken from actual test papers. Students will get an email from NIETS telling them where to go among NIETS' headquarters in Bangkok and its 18 branches across the country.

Uthumphorn dismissed complaints by students and parents that the answers to 11 questions in Thai and social science had problems, saying the 11 answers to the 11 problems were correct.
