how do i end my letter?...yours sincerly, yours truly, sincerly, tha.......

Hi,

If you want your letter to be grammatically correct then you will need to look on the internet for more exact guidelines or speak to a tutor. In correct English there are exact endings for each type of start.

In my opinion, English is a lot more flexible than this comment suggests.  Please review the earlier comments in the thread for some good advice.

Best wishes, Clive

Daniel i'm not sure how to end a letter like that but i'm thinking along the lines of Academically Yours. Also it's sincerely not sincerly. I don't see a problem with you not taking twelfth grade as long as you graduate with a high G.P.O. you should be fine. Many students complete school early by getting a G.E.D. i'm not stating that it's good. Due to a life altering situation i had to graduate early and now must go through community college before i can even think of anything else.

I wish you luck,
Lisa
