Is it useful to prepare the examination materials recommended by CDA data analysts and management houses? Do any seniors who have passed the exam give some advice?

It must be useful. First of all, as an online educational information platform, Management House is still very influential in China. For data analysts, it is a professional interactive learning paradise. In addition, the Economic Management House is the only organizer of the CDA data analyst certification examination in China, and the Chinese certificate in the CDA certification certificate is certified by the Economic Management House. With these factors, the learning information and reference materials of the management house will be more valuable than the materials we found on the Internet.
