Could I continue CA later?

A student who has cleared CA Foundation and Intermediate Group 1 is concerned about resuming their studies later due to work commitments. They want to know if they'll need to retake the exams they've already passed, especially if the syllabus has changed. The advice given is that they won't need to re-appear for cleared exams, but the student is still seeking clarification on how syllabus changes might affect continuing with future groups.
