first thing you do is read a few books, find a stable that has there own horses and allows you to tack up your own horse(Saddle blanket, Saddle, Bridal.
Preferably one that has an indoor arena
A mare has a udder with two teats, they are not obvious. you can't see them unless you are grooming near the legs.
A mare is older than 5years
A filly is a female younger than 5 years
A colt is under younger than 5 years. a colt is a male
A gelding(Castrated male horse) you can see from a distance.
A stallion, uncastrated(Same as Above)
THe first things you should learn about is How to be safe with horses, they are big, tempermental, LIVE ANIMALS.
you need to lern how to tie them up, Groom them, including correctly picking out the hooves. then you will learn how to tack them up
you will probably get help the first couple of lessons with tacking up.
You will probably learn to walk (4 beat gate )and (trot 2 beat gate.) sit and Rise(slight out of the saddle when the outside front forleg goes forward( you should be out of the saddle.) (when the inside leg is leading you should sit.)
you will probably learn to jump before you learn to canter. then when are confident in trot and your instructor thinks your ready, ask the horse to canter (inside forleg has to be given the appearance of leading.)
i had learnt to control horses as i learnt to ride on a trail ride(don't reckemend that thuogh) most scoolies are confident beginers horses.
I had a nervous horse, for my first pony club, she was a black mare Throughbred x Quarter horse we had free time at the end of the lesson, near the end of year 7 and at this particular point i could only walk and trot. i saw a log, i though i'll give it a try, i turn to go to end of the arena and she spooked, we approached the log at a blazing GALLOP, (SHE HAD A BAD HABIT OF REFUSING FENCES And then she would jump them when you didn't expect her to) in the case i was in it was safer for me to go and gallop madly over the log then pulling her up before the log, i just shifted my weight forward, like a jockey down a race track, i hope she would go over, she did and the lady who was running the lesson, said, SLOW DOWN. IMAGING LEARNING TO GALLOP BEOFRE LEARNING TO CANTER!, it took a while for me to learn to canter because of that, but i love to jump.
