Overwhelment and anxiety

I am a final student currently pursuing my internship. Often while studying, I start worrying looking at the volume of the syllabus and feel down. My exam is a year away and I have done 60% of accounts, 60% of sfm and completed costing. Firstly, I want to know if my pace is fine and whether I am on track. Secondly, how do I deal with this sense of anxiety because it doesn't let me focus. Any advice will be greatly appreciated. TIA.
