From Wikipedia:
The Java platform (Enterprise Edition) differs from the Java Standard Edition Platform (Java SE) in that it adds libraries which provide functionality to deploy fault-tolerant, distributed, multi-tier Java software, based largely on modular components running on an application server.
The syntax is the same. Everything you learn pertaining to Java SE will apply to Java EE. It simply adds a pile of new APIs, and calls for a certain style of application design that is well-suited to specific types of problems. Those kinds of problems (large, fault-tolerant, distributed, scalable, multi-tier...) and how to solve them are really what Java EE is about, not the actual APIs that happen to be part of the specification.
Remember that a CS degree isn't a vocational degree. It is meant to teach you how to learn and think, not train you in a specific skill-set tailored for a certain industry niche.
