I haven't taken TeckChek myself, but by visiting its website, i was able to notice that there are multiple Java tests listed there. I'm copy-pasting them here.
JAVA 2 PROGRAMMING
JAVA 2.0 NETWORK SECURITY
JAVA DATABASE PROGRAMMING WITH
JDBC JAVA DISTRIBUTED PROGRAMMING
JAVA
J2EE JAVA NETWORK PROGRAMMING
JAVA SERVER SIDE PROGRAMMING
JAVA SWING DEVELOPMENT
So, if you're asked to take "JAVA 2 PROGRAMMING" test, then I would assume it would be like the
SCJP exam.
