Thank you for all the advice and resource ideas. It was really helpful. I just passed the OCAJP exam with 80%. I had only one month to prepare during my winter holidays.
Not to mention that I had a brief idea about the language before.
This is my first certification and I am extremely grateful for the information that I got from the ranch.
Thank you everybody.
I am now heading to OCPJP now. I would appreciate your support!
