Help! Having trouble with D336

Hey guys I’m having trouble for d336! I watch session 1,2, and 4 of the cohorts. I watched the value insights and even got the itil 4 app everyone talks about. I’m only passed once on the practice exam for the app. I’m still feel uncertain on it. Any advice on where I should I go from here. I spent 11 days on this class was hoping to complete it by the 14th but I feel uncertain I’ll pass the exam. Is there any other practice exams I can take that will give me feed back on what sections I need to brush up on?
