Depends on the balance of payments. If the value of spending this 20 thousand is greater than this 20 thousand, it is worth it, and vice versa. Personally, I feel that it is a bit expensive to send a core article of 20 thousand. How much is sci? I feel that the paper is not too difficult to write, and it is at least the core. So write it yourself. But if you are an office worker, you probably don't have that much time. I suggest finding a cheaper one.

How much does it cost to publish SCI papers \ core journal papers?

Market status of popular science agents;

1. At present, the price of most periodicals of North Nuclear Power is 2.0+.

2.c magazine is very professional. At present, a small number of agencies can operate C magazine at a price of 3.0+.

3.3. Most companies in SCI can operate 0-2 points, and the price is 3.0+.

Don't talk about general problems, there are hundreds of thousands.

5. The price of statistical sources is generally around 1.0, and some publications will be more expensive (like nursing).

6. There are some dual cores, and this price will definitely be higher.

If there is anything wrong, consider me talking nonsense. Don't be serious!

At present, the publications collected by HowNet are the most expensive, and each edition requires a second edition. Page fees are basically above 1500-2000, depending on the relevant requirements of your organization. If it is an intermediate or provincial periodical, there will be a publication as long as it is paid.

If you want to send the core, the price will be high, and the market is complex and easy to be fooled. So the core must be cautious. You can ask Paper Net, a citizen, because I have published national journals in that field before, and now they give me free guidance at the core. Although it has not passed the audit of core journals at present, at least the institution is trustworthy.
