More important than prayers is to study the manual very carefully and thoroughly; and to practice driving a vehicle many times prior to taking your driving test.
Remember that old expression, “The Lord helps he who helps himself” (or in your case, “she who helps herself”.
While prayer is important, being fully and properly prepared is even MORE important. Remember, an automobile (or a motorcycle/scooter) is a potentially lethal weapon, and it is vitally important that YOU be properly prepared to operate one before you are allowed to go out on your own on the roads.
