## Computer Science New syllabus (first examination 2027)

Note: some of the topics/subtopics **won't** be covered by hackmd notes. Some other intersecional topics (such as command terms) will be addressed in specific notes. Here you have the structure as is in the syllabus so is easier for reviewing.
