Curriculum Education Research is definitely not a core periodical, but a general provincial periodical. Remember two points: first, core journals do not send advertisements to your mailbox. Once they receive an advertisement, they must be an intermediary and ask for money; Second, if you invest in core journals, you must accurately find the contact information of the editorial department of the journal and submit it after confirmation. Most people who spend more than 3000 yuan on a page will be fooled. Believe it or not.
