Need advice

So i have my final year university practicals from around 4th of march, I've not studied for practicals seriously until now, and our college has a streak of failing atleast 25-30 students out of 200. I've started studying and going to the wards since the last 2 days....cant focus tho because we had our theory exams till 31st jan. My batchmates have started studying since a week tho. All my theory exams were not-bad except for surgery 1. What approach is the best for studying for practicals. What if i get a very uncommon case? This anxiety is not allowing me to study. Is it possible to pass practical exams in a span of 10 days?
