Get the Barrons book on CSA. The practice tests were harder then the AP Exam that I took last May. Learning the concepts effectively is not that hard. You just need to take notes on specific topics that are essential for the FRQs. Each FRQ has one coding concept that you need to use so if you just memorize what to type for the FRQ, the FRQ section will be light. As the MCQ portion, I would just go on AP Classroom or something and know what iteration are since those come up the most on the AP Exam. Since you havent had coding experience, just take this test like a memorizing test tbh. Know what code does and constantly repeat it. To conclude, just get the Barrons book and if you do well on the practice tests, you will easily get a 5 on the Exam.
