My Friend Has Been Withdrawn From School, Should I Tell Her?

I am a level 200 student in a school here in Nigeria. I went
to check our results for last semester, and she was withdrawn because she failed about eight courses.
Came back today, she asked me about it, I told her she passed although I didn’t tell her I saw it, just told her the lecturer said so, now she’s happy and celebrating, not knowing she has been withdrawn, am restless, I feel pity for her, should I tell her the truth or just pretend all is well.
