Beginners may want to level up their character all time in Requiem. Here is the basic introduction Which I found from the other website on how to level and EXP tables. Each character's strengths and abilities are measured by their level. A character's level begins at 1 and can increase to a maximum of 69.

They must earn Experience Points in order for a character's level to increase. Experience Points ("EXP") can be gained either through killing monsters or completing quests. EXP can be lost through character death. The amount lost scales to level and is roughly equal to 5% at level 10 and 1.5% at level 60. Character death can never lower a character's EXP to less than 0% and so will never result in the loss of a level. Each time a character gains a level, that character gains a single Skill Point which can be used to learn a new Skill or to develop a Skill already learned. Additional skill points are granted after Class Changes and upon achieving levels 30 and 60. Each level gained also increases the base Stats of a character by a set amount dependant requiem lant  on the character's class choice. Additionaly, a higher character level allows access to higher level equipment and quests (both of which are all character level restricted).

Skill Points or Class Changes and Awakenings below for the details of additional skill point gains.

2)First and Second Job(Class) Changes and Awakenings
At certain points in a character's span of levels, advancement of EXP is suspended and a character must complete a Class Change or Awakening Quest before they are allowed to advance further. These Quests were removed with the release on Thursday June 19 and the Temperion's Qualification Quest for a Temperion to acquire their First Job was replaced by the First Choice Quest.

3)First Job(Class) Choice
All characters start off as a Temperion. Temperions are limited to a maximum of level 9 and 100% EXP. Upon reaching level 9 a character can begin the quest Temperion's Qualification. Upon completion of the quest, a character must choose a First Class to advance to. Doing so also raises a character's level to 10, allowing further advancement in their new class of choice.
