Is it selfish to not let others copy off my work that I worked so hard on?

Thank you for your comments everybody. I just needed a second opinion on this.

Thanks. Could be a way to build social networks but this is not just a one time thing. And it gets worse and worse. It starts out as a “help” but it ends up me doing the whole thing. The case now is taking my old work, striking off my name and writing theirs. I don’t think I’ll be telling the professor and complicate things. And as it is mentioned here, that could get me in trouble.

Thanks. I’ll take your advice and say “no”.

I could opt to do the project alone but they come and ask to form a group. I just see it as writing extra names on the project. What made this situation worse was that other groups were asking me to give them my work.

I didn’t know it was this serious. Thanks.

I didn’t know this could get me in trouble. I’ll take yours and others advices and say no. Thanks
