This is to inform you that the course date is too close to be able to ship hard copies of the material to you on time. If you are willing to use the material in secured PDF, receive the material later (likely after the course) and pay upon registration, please click OK to continue the registration process. Please note that the shipping process will start only when the course fees are paid in full and delays are to be expected. Many thanks!
