Some of the questions were tricky, some were ambigious. But overall, 61% is too easy for a passing score.
Here are the resources I used:
More
servlets and
JSP by Marty Hall
- The book contains much more information than you need. Very informative.
API spec(javadoc):
- Indispensable.
Servlet 2.3 and JSP 1.2 specs
- I used it a lot. But for the exam Marty's book is probably sufficient.
Marty Hall's exam reviews:
http://courses.coreservlets.com/Course-Materials/15-Web-Component-Certification.pdf - Great for the night before.
Miftah Khan's Note -
http://www.javaranch.com/carl/scwcd/servlet_study_guide.rtf - Great for the night before.
