It might not always appear to be true but for most of us our school days are the best days …..
I can honestly say that thanks to my form tutor and headmaster at Holyrood School Barnsley I was provided with confidence and self belief that what I wanted to be was achieveable ….. to be an artist , so I would say listen to your teachers they are there only to assist you and as much as you may think otherwise they only have your best interest at heart.
Also remember there are many different ways to learn with art and creativity just as important as core subjects. We all have different skills and talents that make us who we are so value them.
