I had joined Indiastudychannel revenue sharing I got $2 clicks in a day from Indiastudychannel page in my adsense account I found it shows the site and the impressions and earnings how can I find which page in that site generated that earnings.
If you have no control over the site such that it can't be linked to analytics or you can't setup specific channels for the pages then you probably can't tell.
If its your own site, you can set up channels so you can monitor which ad or webpage is performing. But your post sounded like you are just a member of that site so like what was said above, if its not your site, you dont have control over it.
