Do you have to complete the online activities that are featured within the weekly work? I know you don't get graded on the answers to these but I focus more so on the actual assignment that is due rather than the activities. I'm getting high grades without doing these but just wanted to know if I'm fine not doing them?
You don't have to do them if you don't find them helpful. I often skip them. In theory I suppose it's possible that a TMA could ask for proof that you've engaged with them- you could skim the upcoming TMA to check. But I'm 12 modules in and have never seen them ask for that.
