I miss the feeling of real exams

for context this is my second drop. And lately I feel like I'm not putting my complete efforts for any test. And it is intensified since I'm preparing at home. Although I do have offline test series. It's just not there anymore that feeling which used to be in school. And that sucks because I feel it might be one of the reasons my scores won't improve even I have done everything. The point is even with offline tests these mock tests don't feel like they have real consequences so it never invokes that exam kind of feeling. I used to be really competitive back when I was in school but now nothing feels like the real deal. How do I overcome this?
