syllabus and study schedule

I am new to 7sage and I am a repeater. When studying, I hear a lot about the "core curriculum" and wanted to know how to use it. Should I go directly by the syllabus or should I study by the study schedule? Either way, is the recommendation to finish the syllabus and/or study schedule before incorporating practice questions or incorporate practice questions along the way? Please explain how this platform works.

Thanks and happy studying
