Providing assignment help itself is not illegal, but it depends on the specific circumstances surrounding the assignment help. If the assignment help is in the form of plagiarism or cheating, then it would be considered unethical and could be illegal.
For example, if a student hires someone to write an entire assignment for them and submits it as their own work without acknowledging the original source, it would be considered plagiarism and could lead to consequences such as failing the assignment or the course.
However, if the assignment help is simply providing guidance, feedback, or resources to help a student complete their assignment, then it would be considered ethical and legal.
It is important to always check with your educational institution about their policies on assignment help, as some institutions may have specific rules and regulations regarding the use of external assistance.
