I am looking for a job. I've seen a lot of job offers online, but it all looks suspicious. Tell me where an ordinary student can earn money online legally? Thank you in advance.

You are right, in the network you can find a lot of questionable offers about earnings. I don't recommend that you buy into it. Better try yourself in the field of writing, for example here https://writingcreek.com/for-beginners/. This is a great solution for beginners, especially for those who have no experience at all, but have a great desire to earn. I am sure that you will succeed.
