Mr. Briggs is an excellent teacher with a love of history. His books always provide very detailed and are usually good for AP classes. the little details and stories he has are always worth listening to. He never ever gives up on kids who put forth work. With Mr. Briggs, he's like life: You get out of his classes what you put into them.
He's a very smart man, but if you don't absolutely love history, you will hate his class. He's really tough, and doesn't even attempt to make the class interesting. If you hate history, avoid his class at all costs.
