Now, a bit of context: I'm in college and my classmate is one of those who are pretty bad at almost every subject, makes jokes about failing everything all the time and answers almost everything with "I don't know.". So, my physics teacher tell us we are going to do a project on pairs at the lab. We couldn't choose our partner, unfortunately, and that classmate (I'll call her N) ended up being my partner. I already knew things would go terrible because we had a chemistry lab project before and her partner (who is the smartest and most hardworking girl in my class ironically) had to do it all on her own because N didn't know how to do anything but since I had no "good excuse" to change partners they wouldn't let me and I didn't want to start a drama since, before working with her, I thought she was very nice.
The lab part was "easy" but very very tiring and boring. It was basically observing a pendulum and counting in how many seconds it made 10 oscillations in different scenarios. No big deal if we didn't have to do that more than a 100 times, literally. So that means I had to focus on the pendulum more than a 1000 oscillations counting one by one without mentioning the times we had to restart because of something. It was 6 hours of counting, 3 hours each day. So yeah, not hard of course but, at least for me, exhausting. And I did it all. Changing the balls and other stuff we used, counting everything, making all the maths and writing, using and organizing all the data. Everytime I told her to do something N said she didn't know how to do it and even if she finally tried something she would do it so wrong that I ended up doing it again because we were losing a lot of time.
Now that that part is done, the real project begins. We have to use all the data to make a report and that's what's going to be marked and if we fail we'll fail the subject even if we have a 10 on the exam. We started yesterday and I can't believe it but she is even worse at making this report than doing the lab work. Whenever I'm not writing I have to read what she is doing because she is either coping from my teachers guide or writing things that makes no sense and repeating herself. So, I write my part and rewrite hers almost entirely. I talked to my other classmates about it and they told me it'd be better if I do the project on my own but N feels bad for not helping on the lab and is constantly asking me to do it together or give her something to do but I'm 99.99% sure that I'll have to redo whatever she does at this point. I only give her credit for doing a couple of drawings (which are a few sticks and the ball and naming the parts) and a graph (she only had to write the data on an app that did the graph automatically). It's nice she did it but considering everything I'm doing, I still feel like it's not enough.

So, WIBTA if I told her to just stop helping me? How can I explain her the situation without hurting her feelings too much?

Btw, no, I can't change partners. Every group has different data from the experiment and all the lab work is done. And we have another project several weeks from now and she would still be my partner for that as well

Thanks for reading

getting mad at my classmate for wanting to help on the project when she's just making me work more and harder
