A Leadership Position

<p>So for "Student Parliament" (SGA), i was a "substitute representative" in 11th grade. Now I'm a full "representative" as a senior. On the commonapp activities section for the positions part should I either say I was rep 12th grade and a substitute rep 11th, or should i just put rep 12th grade and not say anything for positions for 11th but mark that I also participated in the activity in 11th grade</p>
