It’s best to follow the school booklist. Just to share my own experience this yr, I brought the textbk n workbook from Popular, imagine my p5ds is thr 2nd batch under this new syllabus but who knows, a few of his classmates and him got 2 pages of worksheets missing?? I’m not sure where his classmates brought theirs. Ds told me his Sci teacher went to bookshop to queestioned the shop lady. So this year I ordered all from school bookshop.Therefore if booklist don’t have this Sci book better don’t buy first.
