If you take the corresponding H12-221-ENU exam within 60 days of purchase and do not pass, you can apply for a full refund under our money-back guarantee. Send a scanned copy of your exam enrollment slip together with the official Score Report PDF within 2 days of your exam date, and your claim will be processed within 7 days. Keep in mind that the candidate name must match the purchaser name, and the guarantee does not cover attempts made within 3 days of purchase, materials that were downloaded but never used in an actual exam sitting, free resources, or expired orders. If you would rather keep studying, you can swap the refund for two free exam products of equal value while keeping the update service on your original purchase. Delivery itself is instant: the files are emailed to you within one minute of payment (if nothing arrives within 2 hours, check your spam folder and contact our support team), and there is no limit on how many computers you install them on.
The passing score for the H12-221-ENU exam is 600/1000, and the official registration fee is USD 160. Remember that an unsuccessful attempt means paying the full USD 160 again to retake it, so booking too early is the expensive way to find out you are not ready. Test yourself with the Exams-boost practice questions first; once you can clear 600/1000 comfortably on timed runs, scheduling the real exam becomes a much safer bet.
