Passed on my second attempt. The first time I try by myself, fail with 40%. The second time I purchase Hitachi HQT-4420 exam guide, it is valid. Pass with 92%.

I passed the HQT-4420 exam last week with your help. If there are someone looking for a good material to guide your certification exam, this is a good choice.
