We want to write on campus because we will not be able to use the invigilator app due to different reasons but mostly due to not having a suitable smartphone to capture necessary pictures. Most students tend to loss many marks online so we think it's unfair for all students to write online because some don't have all necessary information and tools to get the highest marks.It must not be mandatory for all students to write online, everyone must have a right to choose which one will work for her/him, either online or contact.
