When you set up your school, the plan shows NGN 0 for one year, and you don't need a card. > It won't be free forever. Lena will tell you before billing starts. > [accordion] Do students pay? > > No. Students never pay for Lena. > [accordion] Do I need a different account for each app? > > No. One email and password work in Lena for Schools, Lena for Teachers and Lena for Students, and at every school > you belong to. See [schools and profiles](https://support.lena.africa/get-started/schools-and-profiles.md). > [accordion] Can I use Lena on my phone? > > Yes, for everything. Open the app's address in your phone's browser. You can add any of the apps to your home screen > so it opens like any other app. See [Lena on your phone](https://support.lena.africa/get-started/phone-and-offline.md). > [accordion] Does Lena work without internet? > > Yes, for a lot. All three apps open offline with your current courses. Students can keep answering a quiz or exam > they've started, and hand in assignments, quizzes and exams: Lena sends them when you're back online. Teachers and > admins can look at what's saved, but changing anything needs a connection. See > [offline](https://support.lena.africa/get-started/phone-and-offline.md#without-a-connection). > [accordion] Can parents see their child’s grades? > > Not yet. There are no parent accounts. ## For students > [accordion] How do I join a course? > > Choose **Enrol**, then tick courses you're eligible for, or choose **Enter code** and type the code your lecturer > shared. You're in straight away. See [join a course](https://support.lena.africa/students/join-a-course.md). > [accordion] Can I resubmit an assignment? > > No. Once you submit, you can't change it or submit again. Check everything before you choose **Submit**. See > [assignments](https://support.lena.africa/students/assignments.md). > [accordion] Can I retake a quiz? > > Only a practice quiz. A graded quiz, and every exam, has one attempt. See [quizzes](https://support.lena.africa/students/quizzes.md). > [accordion] Why can’t I see my quiz or exam result? > > Your lecturer hasn't released them yet. Some quizzes and exams release results by themselves when the quiz closes or > the exam ends. Practice quiz scores show straight away. > [accordion] Why are my grades 0, or so low? > > Every published assignment, quiz and exam counts towards your total. Anything you haven't handed in, or that hasn't > been released yet, counts as 0 until it's scored. Open a course in **Grades** to see "Missing work". See > [grades](https://support.lena.africa/students/grades.md). > [accordion] What happens if I leave the page during an exam? > > Your exam isn't submitted, but you have to wait before you can carry on, and the timer keeps running. The wait gets > longer each time you leave. See [exams](https://support.lena.africa/students/exams.md). ## For teachers > [accordion] Why can’t students see my course? > > It's still a draft, or they aren't in a group allowed to join. In the course's **Settings** tab, set **Who can > join** and how much assignments, quizzes and exams are worth, then publish it. See [publish a > course](https://support.lena.africa/teachers/publish-a-course.md). > [accordion] Why can’t students see my quiz? > > It's still a draft. Add at least one question and choose **Publish**. Students can take it from its start time. An > exam also needs **Approve** after **Publish**. See [quizzes](https://support.lena.africa/teachers/quizzes.md) and [exams](https://support.lena.africa/teachers/exams.md). > [accordion] Why did students who didn’t submit get 0? > > Releasing an assignment's grades gives 0 to everyone who handed nothing in, and closes the assignment. See [grading > and releasing](https://support.lena.africa/teachers/grading-and-releasing.md). > [accordion] Can I edit an assignment or quiz after publishing it? > > No. Once published, it can't be changed, so every student sees the same thing. You can choose **Extend deadline** on > its page, or choose **⋮** → **Duplicate** (**Duplicate quiz** for a quiz) to make a new draft copy. > [accordion] How do I add students to my course? > > Students add themselves. Students in the groups under **Who can join** can pick the course from their list. To let > anyone else at your school in, share the entry code: open the course, choose **⋮** → **Copy entry code**. Anyone > with the code can join while the course is accepting new students. See [join a course](https://support.lena.africa/students/join-a-course.md). > [accordion] How do I get Lena Agent? > > Lena's team switches it on for each school. Until then, choose **Request access** where you see "Lena Agent isn't on > for your school". See [Lena Agent](https://support.lena.africa/agent/overview.md). ## For schools > [accordion] Can we change our school type later? > > No. You choose University, K-12 or Other when you create the school, and you can't change it later. Choose the one > that fits best. See [words your school uses](https://support.lena.africa/get-started/words-your-school-uses.md). > [accordion] How do students get their sign-in details after an import? > > Straight after importing, choose **Download sign-in details**. You get a PDF with every student's sign-in details. > You can only download it then, so keep it safe and give each student their own details privately. See [import > students](https://support.lena.africa/schools/import-students.md). Still stuck?
