Why do we need to revise the K to 12 Curriculum?

(1.) What are the three curriculum review findings?
a. curriculum content is congested;
b. misplaced pre-requisites;
c. _____________________________?
(2.) Other than the shifting local and international landscape in education, what are the other contributors to the development of the General Shaping Paper and the MATATAG Curriculum?
Dismal results in local and international large-scale assessments (ILSA) and internal benchmarks
All these reasons paved way to the need to revise the curriculum.
