Struggling with NBCC exam on NBCC practice tests — any tips?

I've done 14 practice tests now and my scores on NBCC exam questions are consistently lower than everything else.

I understand the concept when it's explained directly, but when it shows up in a scenario or application question I freeze up. It's like my brain knows the theory but can't connect it to a real situation fast enough.

Currently spending extra time on "NBCC" study material but I don't feel like it's clicking. Has anyone dealt with this and found a specific approach that helped?

Things I've tried:
- Re-reading the textbook section (not helping)
- More practice questions on this topic specifically (some improvement but not enough)
- Watching YouTube explanations (hit or miss)

Any advice on how to actually internalize this concept rather than just memorizing surface-level facts?
