Hello! I'm a PN (practical nursing)student preparing to take for the ATI Proctored Assessment PN Mental Health and the ATI Proctored Assessment Dosage Calculation in April of this year. We've been studying on Tutorial learning system PN Practice, ATI Assessment Mental Health online practice A and B, and ATI Tutorial Dosage Calc online. Last semester I failed and had to do remediation for the materials failed and lost 10% of my overall grades in the class. I had a 87% average that went down to a 78.3% I was devastated to say the least. Is there any advice, insight, resources, materials, course reviews, you can give or send me to improve or excel in this oncoming online exam
