What learners say

Feedback from people who studied 1Z0-819 on NerdExam.

Lambda expressions finally clicked. Cleared 1Z0-819 first try.

ahmad_uaeJunior developer

Good coverage of exception handling, which trips up a lot of 1Z0-819 candidates. A few questions felt repetitive but the explanations made it worthwhile.

asante_accSoftware engineer

I was mid-study when I found NerdExam and it changed my approach to the localization and I/O sections. The questions go deeper than just memorizing syntax. Passed on my second attempt and feel confident in the material now.

The JPMS questions here are exactly what the exam needs.

Oliver D.Backend developer

I am a senior dev who thought I could wing this exam on experience alone. I was wrong - the concurrency and generics sections humbled me quickly. NerdExam's questions on those topics pushed me to actually study the gaps.

neha2kSenior developer

I struggled with streams and Optional chaining until I worked through the practice sets here. The explanations after each question finally made it stick.
