A character's knowledge is represented by his/her "fields of knowledge". Fields of knowledge are required to perform many tasks (see Resolution), and in such cases, the more relevant knowledge the character possesses, the better the modifiers he/she will receive to perform the task.
Basic is the cost (in Educ or years of part-time study) required to learn the basics of a field. (Record this on your character record as "basic <field name>".)
Standard is the cost (in Educ or years of part-time study) required to gain a thorough grounding in a field.
Specialisation. This is the additional cost (in Educ or years of part-time study) required to learn a specialisation within a field. Specialisations constitute deeper knowledge of specialised subjects within a field.
TL (tech level) represents the level of technology required before the field becomes available.
