Speed ramping practice

We learnt an edeiting techniue in class "Speed ramping"
This technique gradually changes the speed of the video clip, the action changes between slow motion, standard speed and fast motion
 we brought our laptops to school in order to practice speed ramping, we sat in pairs and started off with editing, Me and Yumna paired up with one another and were giver a total of 10 marks and each time we asked sir for help 1 mark would be deducted and if we would be unable to complete the task in time we would be marked zero 
we got 9 out of 10 in this exercise
