How to purchase Java Certification exam voucher from Oracle India?

1. First, you have to register yourself on Oracle's site.
   
   
2. Next, use the links on the above mentioned page to go to the correct certification page. The site is a maze, so you will have to go through several pages. Eventually, you will have to reach this page: Direct link to OCA Java 8 1Z0-808 certification detail page. Here is the link for OCP Java 17 1Z0-829 exam. As of March 2023, the exam page looks like below:
   
   
   
   Click on "Buy Exam" button to reach to the following page:
   
   Select the "Oracle Cloud Infrastructure and Technology Exams" and click on Add to cart. If you want to take the Java Foundations 1z0-811 exam, select " Oracle Foundations Exams for Students" option.
   
   You can click on "View Details" to see the exams that you can take using this voucher.
   
   
   
3. You can pay for it using Credit card, but most of the times, Credit Card purchase fails. Even though the card is valid, the transaction is rejected without giving any reason. Usually the reason is that Oracle charges in US Dollars but Indian cards do not have international payments enabled by default. If it fails for you, use the Electronic Funds Transfer (or Wire Transfer/Bank Transfer) option to purchase. This option allows you to pay through NEFT/RTGS.
   
4. After entering student and customer details, select "Electronic Funds Transfer".
   
   The "Reference Number" field is for your own reference. You may enter any number here. Later, you may specify this same number in the NEFT details (if your bank allows it, otherwise, you can ignore it).
   
   If the Electronic Funds Transfer option is not available, use "Wire Transfer/Bank Transfer" option. In the "Wire / Deposit" text box, enter "Wire Transfer" as shown in the image below.
   
5. You don't have to pay them at this time. Just complete the check out process. This will create an order with an order id such as o1234567. You will also get an email about it with an invoice containing the exact amount that you need to transfer. They will use the reference number that you entered above on this invoice. After a couple of days, you will get another email with Oracle's bank details:
