I think it is still a perfect time to improve your skills by taking the DB2 Fundamentals Exam. You'll earn a Database Associate Certification and will be better aware of how strong your skills are. In times like we have today where there are many people looking for jobs, it is best to try to have as many skills as possible and to have a way to distinguish yourself from the others.
Until the end of April, if you pass the assessment exam, you can qualify for a voucher for half off the cost of a certification exam. See my blog entries for details: http://www.ibm.com/developerworks/blogs/page/SusanVisser?tag=certification
I hope this answers your question. Let me know if you need further information.
