Depends on what you mean by “take pride”.
If you’re just happy you did well, and you give the glory to God for giving you the ability and resources to do the project, and you share credit with any team members or teachers who helped you, and you don’t brag or think you’re better than others and you maybe even try to help others who can’t do projects as well, like help them learn or improve, then it’s not sin.
If you think you did it all yourself without God’s help, that’s a sin.
If you brag, that’s a sin.
If you feel you’re better than others because you do good projects, and start getting a big ego over it, that’s a sin.
If you lord it over others that you did well, that’s a sin.
If you don’t share credit with others who helped you, that’s a sin.
If you don’t try to help others when you can, that’s a sin.
