first you should print out circle cut out online the see if hes better than if he can do it then hes fine

You are describing possible issues with fine-motor skills.  While I am not sure that your description indicates a problem (for example, do you mean he can not write letters or that he does not scribble with a crayon?), the place to check for fine-motor problems is an occupational therapist.  Your pediatrician should be able to guide you.

Thank you for your replies, he does scribble but that is all, he can not draw a circle, he can close the scissors but he can not open it. Seems like he does not have the thumb coordination. I will check into occupational therapy and try some things at home as well.

When my son was 3 he started drawing circles, cutting with a scissors, but he didn't say a word.  Testing would reveal that he is severly autistic with great fine and gross motor skills.  Almost all states have early intervention programs for children.  Contact your school district and they should be able to tell you where to go for testing.  Your son may be eligible for occupational therapy services at no cost to you.  P.S. my other son has awful fine motor skills, terrible handwritting and can't cut a straight line, but he's an excellent student & a great debater.  Seek assistance from experts before you worry too much.

When working with drawing skills, its important to think big movements first and proceed developmentally.  A child learns to draw straight lines first and then circular ones.  Practice with large movements using sidewalk chalk, painting on a big piece of paper.  Our larger muscles appear to have better motor memory than our little fingers.  Also for cutting, check out loop scissors which open on their own and do not require fingers in loops at www.therapro.com
An occupational therapist would definitely help with your concerns.  Just find one that you are comfortable working with.
