The LabTutor Student login uses iconography to quickly indicate the status of a given Experiment. The Icons are as follows:
The 'Pencil' icon indicates that this Experiment has been Started (but not Submitted)
The 'Tick' icon indicates that this Experiment has been Submitted, and cannot be edited any further
The 'Lock' icon indicates that an Adminstrator has manually locked this Experiment. This Experiment has not been Submitted, but also cannot be edited any further.
The 'Globe' icon indicates that this Experiment has been Started or Edited in LabTutor Online. Note that an Experiment Started or Edited in LabTutor Online cannot be worked on on-site - it must be completed in LabTutor Online.
The 'Information' icon is usually paired with the Experiment being greyed-out and inaccessible. This can be indicative of several issues (primarily Grouping issues). Hover your Mouse Cursor over the icon to see a description of the issue.
