Hi Priyanka, The below info might be useful for you, if not please let me know will try to make you understand it clearly. OCJP Costing When there are differences in the currencies accepted by Oracle University and the test vendor (Pearson VUE) for a particular country, the exam price (Fees for Vocher) will be provided in the currency offered by Oracle University. In these cases, candidates can either (1) purchase a voucher through Oracle University in the currency offered (usually local currency), or (2) purchase the exam directly from test vendor at the currency offered by the test vendor. Candidates will need to check exam prices to confirm the currency accepted by the vendor for the selected exam. Exam price currency conversions are reviewed and updated annually at Oracle, and due to daily currency rate fluctuations – the USD price may not always exactly map to the stated price in local currency. Note that we will not provide refunds or adjustments for fluctuating currencies. OCJP Exam Scoring Policy Exam Passing Scores: Oracle routinely publishes new versions of its Oracle Certification exams. The passing score for each exam version is set independently to maintain a consistent scoring standard across versions. For example, to maintain a consistent standard for success, a new version of an exam which contains more difficult questions than the prior version will be assigned a somewhat lower required passing score. For this reason, passing scores may vary between different exams in your certification track, and between later and earlier versions of the same exam. Oracle does not recommend an exam preparation strategy targeting the passing score, as passing scores are subject to change without notice. Scored and Unscored Questions: Your exam may contain unscored questions in addition to the scored questions, so the total number of questions that are presented to you may be greater than the number shown on the exam page. This is standard testing practice. You will not know which questions are unscored. If your exam contains unscored questions, the time allowed for the exam takes into consideration the time you will need to answer all questions and review your work. Your exam results will reflect your performance on the scored questions only. NOTE : The cost for the course and some other factory may vary time to time based on Oracle policies. All the best.... read less
