Take the last two digits of your enrolment number and add one to each,

except that if a digit is $9,$ change it to $0.$ For example, if your enrolment

number finishes $75,$ you would get the two$-$digit number $"86".$

Write out this two$-$digit number $($as single digits$)-$ so for example if your two

digit number is $86$ you would write "EIGHT SIX" $($and not "EIGHTEEN"!$).$

Write your message in Morse Code, and calculate how many units of time it

would take to send the message, using the timings given in the lecture

notes.
