Anonymous users2024-02-05The CDA certificate can be taken by yourself, but it will be more difficult.
It is best to sign up for training, the introduction of data analysts is relatively simple, and there are even a large number of students studying liberal arts every year, who are learning the relevant knowledge of data analysts and obtaining CDA certificates.
As long as you like it, are willing to study unremittingly for a long time, study hard, brush up on the questions, and take it seriously, the CDA certificate can be obtained.
The importance of the CDA certificate
Due to the importance and scarcity of the data analyst position, the CDA certificate will continue to be valuable for many years to come. For people who want to obtain a CDA certificate, especially those who have entered a busy workplace and are very busy with work on weekdays, it will be difficult to learn the relevant knowledge of data analysis by themselves and use it to obtain the certificate.
Therefore, for working people, it is advisable to find a professional institution or tutor for systematic learning, which is a way to learn data analysis related knowledge more efficiently and obtain a certificate.
