Became familiar with the exam format

As i was giving the C_S4HDEV1909 certification exam for the first time, i had to be conversant with the SAP Programming in SAP S/4HANA for SAP NetWeaver ABAP Programmer mock test to know how the questions appear, what is the scoring system, how is the environment like. With this, i also got to know what should be the level of my preparation, how should i approach the mocks and what should i do to achieve a score that is good.
