I cannot see my course. What should I do?

Students are enrolled in the Bb courses after the end of Online Late Registration of each semester/term/session. Thus, they will not be able to view their courses at the earliest, until this day.

Why do I see Bb courses from previous semesters/terms/sessions?

Courses become unavailable for students to see two weeks after the end of the Re-sit examinations  (view the Calendars for details about the dates of Re-sit Exams).

In case you do not wish to view past courses you can enable Terms so as to group and collapse them by hitting the gear icon at the top right part of the My Courses module. Moreover you are able to un-check the respective textbox of the course(s) you do not wish to see or click the Select All/Unselect All option under the Edit Course List section.

I can't find an assignment, test, blog or other content in my Bb course.

Your instructor controls the availability of any tests, assignments and other content. So if you can’t view them, it means that the instructor made the content unavailable to students or put some viewing restrictions on it. Ask your instructor about it.

Additionally, you can check the Tools link from your course’s menu and hit the tool you wish to visit and view its contents i.e. Blogs.

I was in the middle of taking a test or writing a post when I lost everything.

Unfortunately, the information is lost permanently. You need to re-enter the information and continue. If the problem persists, contact your instructor.

Some common problems that cause this may be:

  • Browser was refreshed.
  • Connection was dropped.
  • Time out due to inactivity. If you leave the test page open without working on it for a period of time, the web browser will log you out of Blackboard and so you will lose any work.

To avoid these problems please follow the following tips:

  • Don’t close the web browser window.
  • Don’t refresh the browser.
  • Don’t hit the back button of the web browser or you will receive a page expired message.
  • Save frequently your work to avoid lose of content due to inactivity log outs.
  • Type any text on an external application i.e. MS Word and paste it using your keyboard (Ctrl+V) in Blackboard Learn.

In order your examination to run smoothly you need a stable and uninterrupted connection. For a stable connection we suggest:

  1. Use a wired connection to the internet.
  2. Close all the other open tabs before taking an exam (tabs that are operating with or without internet).
  3. If you are on home network you have to ensure that the time you are taking the exam the other members of the household do not use the internet connection.

Perlego - I have the code from my school but I cannot register.

If you are being asked to start a plan, or the code is not accepted, it sounds like you may have accidentally signed up the ‘regular’ way (this is different to subscriptions provided by your university or company).

Fear not! Just follow these quick steps.

  1. Delete your account via your account settings.

  2. Follow the registration link provided by your school (it should take you to a ‘group-register’ page)

  3. Enter your code and details!

Perlego - I already have a Perlego account.

There is no way to ‘add’ the code onto the account as the sign-up process for institutional accounts is different from regular accounts.

But you have two options.

1. I don’t have annotations, highlights and reading lists I want to save…

In this case, follow the steps:

  1. Head to your account settings.

  2. Delete your account (if you don’t see this option, get in touch with Perlego support).

  3. Follow the link provided by your institution and enter the code you were given.

2. I have annotations, highlights and reading lists I would like to save…

If you would like to keep your Perlego data, we can manually ‘convert’ your account.

Perlego - Delete account.

There is no option to cancel the subscription or delete the account.

As your account was provided to you for free, by the university or institution you do not have to worry about cancelling a subscription – as there isn’t one and you won’t be charged.

If you would like to delete your account, you will have to get in touch with your institution and ask them to ‘revoke your license’. You will then be able to log in and delete your account.
