Some of the courses may require you to take an assessment before you can complete it. When you have completed all the lessons, you will automatically see an option to take assessment.
To start, simply click on the take assessments option.
Please note: When a question requires you to upload a file, you must ensure you provide mobile storage access to the app.
If you denied the app access the very first time, you will be prompted to change the app settings and allow access for the same, when you are required to upload a file.
