There are six primary reasons why lessons may be locked in your SI Cloud course. Click on the lock icon to the right of any locked lesson to show a tooltip explaining why that specific lesson is locked. More information on each possible reason is included in the sections below.
If the "Enter a Code" and "Purchase Kit" buttons appear on the top right-hand corner of the window, that means the lab kit for the course has either not been purchased or the kit code has not been entered. See our guides here for help ordering or activating your lab kits.
All courses include two or three prerequisite courses that introduce you to using the Cloud system to complete your lessons. If these lessons are not completed, the rest of your lessons will not unlock.
Complete all lessons listed under "Prerequisites" at the top of your lesson list to proceed.
When you select a lesson in your LMS, does the lesson list appear? See more information here.
Lessons usually have to be completed in order. If you haven't finished all previous lessons a course, you won't be able to move to the next one. Make sure you have completed all the lessons above the lesson you're trying to access.
The lesson in the example below is locked because previous lessons have not been completed, and is ready to unlock as soon as its prerequisites are met.
Your instructor can set lessons to unlock on specific dates. If this is the case, clicking on the lock icon will show a message with the date it will unlock. If a lesson is supposed to unlock on a certain day, you won't be able to access it until that date.
SI Cloud includes the option for instructors to add or remove questions from lessons. However, until they save and publish these changes, students are locked out of the lesson. Contact your instructor for guidance, as they may only need to publish their changes or they may not intent for you to access the lesson yet.
