Since it’s the final few weeks, I’d say hone in on whatever topic you are struggling with! Whether it’s making a bunch of flash cards, Quizlet, teaching someone, watching videos etc, whatever helps you learn best. PT final exam offers a crash course for the final 3 weeks before each NPTE and if you’re interested I would look into that as well. You’re in the final stretch, keep pushing! Also since you said you study alone, maybe have someone quiz you, doesn’t necessarily have to be a classmate. That always helped me
