The Chemistry or Geography Oral: A University Conditional
A candidate is applying to a Dutch university for Medicine, which requires a final mark of at least 65% in Chemistry. She is taking five written examinations: L1, L2, Mathematics, Biology, and History. For her three oral examinations she must choose L1, L2 (or a replacement), and a third subject. She can choose Chemistry or Geography as the third oral. Chemistry is a 4-period course; her preliminary mark is 58%. Geography is also 4-period; her preliminary mark is 81%. For a subject examined only orally, the final mark is 50% preliminary mark and 50% oral examination mark. The oral examination in Chemistry is known to be demanding: last year the average oral mark was 62%, with a standard deviation of 8. The Geography oral average was 74%. The candidate’s teacher predicts she would score around 70% in a Chemistry oral and 85% in Geography. The deadline for oral choice is tomorrow.
1. Calculate the final mark the candidate would achieve in Chemistry and Geography under the teacher’s predictions. Then determine the oral mark she would need in Chemistry to reach the university’s 65% requirement. Advise her on which subject to choose.

Chemistry final = (58 + 70)/2 = 64.0%. Geography final = (81 + 85)/2 = 83.0%. To reach 65% in Chemistry: (58 + x)/2 ≥ 65 → x ≥ 72. The teacher predicts 70, so she is 2 points short. Given the cohort standard deviation of 8, a 72 is within one standard deviation of the mean (62), so it is attainable but not guaranteed. If she chooses Geography, she will comfortably exceed 65% overall but will not meet the Chemistry condition, so the university place is lost. The rational choice is Chemistry, because the university condition is a hard constraint; the Bac overall average can be protected by her strong written subjects. She should choose Chemistry and use the remaining time for targeted oral practice. The school should not advise Geography merely because it is safer for the Bac average; that would ignore the candidate’s stated goal.
2. What are the risks of choosing Chemistry, and what contingency plan should the school help her put in place?

The risks are: (1) the oral mark may fall below 72, so the final Chemistry mark is below 65 and the university offer is missed; (2) a low oral mark also enters her Bac average, although one subject has limited impact if her other marks are strong; (3) the oral is high-stakes and may cause anxiety. The contingency plan should include: (a) ask the Chemistry teacher for two extra practice orals with feedback against the criteria; (b) prepare a bank of past oral questions; (c) identify a backup university offer that does not require Chemistry; (d) check whether the Dutch university accepts a different proof of competence, such as a written test or a foundation year; (e) rehearse timing and structured answers. The school should also confirm in writing that the predicted 70 is not a cap. The candidate should make the final choice, but the school must ensure she understands the probabilities.
