Clark seemed overly harsh when he yelled at Jerold for shouting. It was true that he had to make an effort to tell Jerold that this was not the way to attract beasts when he was in a dungeon. It was very dangerous. There was also the clear fact that the younger and less experienced first year students had never been in a dungeon.
The elite class received many different benefits. They had a single professor that was dedicated to their growth by whatever means necessary. Along with that were the field trips to the wilderness and the dungeons. These things were because of their status as elites.
The first years that didn't have the benefit of being elites would need to find mentors or funds their own way to fight in the wilderness or the dungeons. Overall, it was something that many people could not afford nor would risk. They were not strong enough to survive the dangers of the wilderness or dungeons yet.
