Six-Type Course Plan
The following content is organized around the six CSCA Chinese question types, keeping objectives, teaching plans, training focus, and practice entry points. The old lesson-by-lesson animation entries have been removed.
Character Recognition
Master the form, meaning, radicals, structure, and STEM context of high-frequency characters.
