DR HON CHIEW WENG, principal, Hwa Chong Institution: 'I refer to Ms Toh Siew Tin's letter on Saturday, 'O-level disadvantage: Six A1s and four A2s - but failed to win a place in first-choice JC'. We congratulate Ms Toh's daughter on her good performance. The cut-off point is calculated using the L1R5 scoring system, and not the number of distinctions attained. This scoring system takes into account the student's first language (L1) and five relevant subjects (R5), which must include at least one from Mathematics, Science and Humanities. Each school's cut-off point varies from year to year, depending on the number and quality of applicants who apply under the Joint Admission Exercise. This year, Hwa Chong's cut-off point for both the Arts and Science streams is 3. This includes bonus deductions for passing Higher Mother Tongue and outstanding Co-Curricular Activities records. We regret that not everyone who puts Hwa Chong as his first-choice school was posted to us. We wish Ms Toh's daughter all the best.'
