I was trying to remember a book series I read many years ago in high school that I wanted to revisit and can not remember any of the titles nor the author. All I can recall is that somehow a man from our time got sent back to medevil eroupe and met merlin. He somehow could change into a dragon and the system of magic was governed like an account with the highest rated wizards being A+++ and receiving the most magic energy to use.
If anyone one has any clue what books I am talking about it would be greatly appreciated :)

Could this be it?

Nine Princes in Amber (1970)Main article: Nine Princes in Amber
Corwin wakes up from a coma in a hospital in New York with amnesia. He soon discovers that he's part of a superhuman royal family that can wander among infinite parallel worlds (called "shadows"), and who rule over the one true world, Amber. He meets members of this newly-rediscovered family, and then later is shown and walks the Pattern, a labyrinth inscribed in the dungeons of Castle Amber which gives the multiverse its order. Walking the Pattern of Rebma (a city in Amber that mirrors the true city of Amber, down to the smallest detail, including the Pattern) restores Corwin's memory and his abilities to travel through shadow. In alliance with his brother Bleys, he attempts to conquer Amber, which is currently ruled by his elder brother Eric, who took power after the disappearance of their father, Oberon. Their attempt fails. Bleys falls from the side of Kolvir and Corwin is captured, blinded and imprisoned. Thanks to his genetic regenerative ability, his eyes regrow and he regains his vision. Dworkin Barimen, the mad sorcerer who created the Pattern, enters Corwin's prison through the walls of Corwin's prison cell, and eventually draws on the wall the door through which Corwin escapes.

Your description reminds me of the Dragon Knight series by Gordon Dickson
I read one of them called The Dragon and the Djinn:

James Eckert--AKA the dragon knight--goes off on another adventure with his friend Sir Brian Neville-Smith. Jim continues his development as a magician who can turn into a dragon and do other transformations and spells at will--but who is warned to be conservative in his use of magic. Jim and his wife Angie originated in our 20th century, but were somehow transported back to an alternate 14th century version of our world where magic is real. Thus the reader gets to learn about the 14th century through the eyes of someone with a 20th century understanding of the world.

Wow the memories that brings back. I never read the official Dragon Knight series which I believe was started in 1990 but I read the original it was based on, "The Dragon and the George", back in the 70's.

I'm glad that jarred your memory. It's a really fun series to read!
