Official-source fact
Subject combinations are part of the official selection journey
The Ministry's Grade 10 selection platform explicitly supports subject-combination selection alongside pathway and Senior School choices.
Practical guidance
Check the curriculum behind a subject
Before treating a subject name as a career label, inspect the relevant KICD Grade 10 curriculum design. The design is a better source for what learners are expected to study than marketing descriptions or informal lists.
Practical guidance
Check whether the school actually offers the combination
A combination that fits a learner's interests is only actionable if an appropriate Senior School offers it. Use the Ministry's selection system or other current official school-offering evidence before making the school decision.
Important boundary
Approved textbooks are a separate question
KICD maintains an approved CBC course-materials surface, including Grade 10 materials. Curriculum inclusion, subject selection and approval of a particular textbook are related but distinct facts and should not be collapsed into one claim.
