As always, if you do not use the proper fingering on this exercise you are just wasting your time! So...here is the proper fingering: On the first four notes in each pair of measures (the ascending notes in measures 1,3,5) should be played with the index finger (finger 1). The four notes (descending notes) in the second measure in each pair (measures 2,4,6) should be played as follows: 1-2-3-4 1 being the index finger and 4 being the pinky finger.

I would recommend that when you do this and other exercises, that you name each note outloud. This serves to improve your familiarity with the neck and also improves your recognition of each note. Happy Practicing!!!
