Trainees whose fancams couldn't be found in Mnet's channel are said to be in either F or X Class,
here is the list of those trainees.
There are some articles saying that trainees from X Class can't even perform on stage.
Apparently Mnet filmed these videos separately to prevent any spoilers.

-Trainees from Woolim Ent....???
-Oh, there's my friend's cousin here....
-JYP...??? I didn't know JYP sent their trainees to this show for this reason...
-What's up with JYP Ent...? And Woolim Ent...?
ㄴOh and is that Sejin who's well-known for Marimong...? I really hope things will turn out well for them...
-Most of them are from well-known companies...
-I saw the gifs somewhere else and they're really that bad...
-JYP, Woolim, and Fantagio...?
-Ah, right... It's possible that they filmed these separately in order to avoid spoilers...
-Maybe it hasn't been that long since he joined JYP Ent.?
ㄴHe has been training for 1 years and 7 months, from what I know...
-There are a lot of handsome trainees in X Class...
-Jungmo, why are you in X Class...? I've chosen you as my pick... I hope you'll improve as the time passes byㅠㅠ Please...
-If you pay attention to the previous seasons, there are some trainees who were in lower class because they did mistake on their evaluation performance. I think we shouldn't be judging them before we watch the full show...
