Hi, welcome in :) there's a thread
here about the variety of evidence you can use. If you include the criteria wording I'm sure members here will help where they can. In the meantime you're probably best speaking to your tutor about when you need to include work products as this can differ depending on the frequency that your assessor comes to observe you in your workplace.
Study buddies do sound supportive the problem is that learners online are in so many different places with their qualification, different awarding bodies, course providers & layout structures that it can be difficult to find what you're truly after and ensure the protection of your personal information. If possible, also ask your tutor if they hold local meetings where you can get a face to face reassurance?
Hth, enjoy the site
