	Content
N(need demand)	1, the verification code is not case-sensitive input 2, set the 7 -day password-free login (considering the teacher will often use at the end of the semester) 3, increase the marking function (for the final period of the adjustment * for the addition of students - for deduction of students) 4, input confirmation (did not enter the completion of a student need to determine the next entry) 5, automatic tumbling (teachers do not need each student to enter, in the input interface from the class 1 start input to determine the automatic jump to the next bit, each interval Ten as a group, for - In a personal class, the teacher just needs to go in. 1 number and 1 can be completed for all students in the class record entry) 6, the page user-friendly settings (according to a teacher's preferences) 7, theAPP version on-line (easy to change the teacher input) 8, automatic error correction (the same student's score gap too large may be wrong hand) 9. Voice-activated input score
A(approach procedure)	1, set up a good security maintenance mechanism (7 - Day password-free login) 2, the existing procedures to add changes (new features) Recruit more technical personnel to achieve these functions
B ( benefit benefits)	1, 7 days password-free landing in accordance with the special period, Special needs of the user 2, auto-roll eliminates the need for users to go into the trouble, But only once can 10 auto-roll to prevent users from having a student Mistakes can be corrected in time 3, App Version more convenient and faster

[ must do 3] using functional analysis Four quadrant method to classify the above functional requirements

Killer function: Automatic tumbling eliminates the repeated clicks of the high-volume score entry, automatic mark detection score
