I once didn't know much on tying neckties until I went to a website and it help me a lot. So now you can just follow those steps I had put on below. Remember you need to try it over and over again cause learning to tie for newbies may not get fast  to complete the whole process, so keep on trying. Good Luck.
Situate the tie so that the end "A" is longer than end "B" and cross "A" over "B".
Turn "A" back underneath "B".

3.
Continue by bringing "A" back over infront of "B" again.
4.
Pull "A" up and through the loop around your neck.
5.
Hold the front of the knot loosely with your index finger and bring "A" down through front loop.
Remove finger and tighten knot snugly to collar by holding "B" and sliding the knot.
