Okay, my guitar teacher gave me this thing to complete over the weekend. Well, i was busy and i have forgotten how to complete this!! Any help would be GREATLY appreciated.
Here is what he wrote:

W = Whole step 1/2= half step
--W----W--1/2-W----W----W--1/2
C----D-----EF-----G-----A------BC
E----F-----?-------B-----?------D
G----?-----B-------D-----E------?

You guessed it, i have to fill in the ?'s. The only problem is, i dont know what to write! I spent about an hour trying to figure it out. But i have absolutely no idea. To anyone who can figure this out. Thankyou SO much!

*EDIT i had to put -'s in between cuz it didnt turn out right before.
