Okay, so I finally sat down to tackle that Unit 4 AP Psychology practice test today. Been meaning to get to it, you know, just to see where I stand with all the sensation and perception stuff, plus states of consciousness. It feels like a pretty foundational unit.

Getting Started
First things first, I cleared off my desk. Can’t think straight with clutter everywhere, right? Grabbed some paper, a couple of pencils – old school, I know, but it helps me focus. Found the practice test online, the one everyone seems to use. Took a deep breath. Honestly, felt a little rusty just looking at the first few questions.
Working Through It
Alright, diving in. The multiple-choice part wasn’t too bad initially. Some questions felt pretty straightforward, like remembering the basic parts of the eye or ear. But then, boom, they hit you with those tricky ones about signal detection theory or the different sleep stages. NREM-3, REM… my brain felt like it was cycling through them too!
I tried not to spend too long on any single question. If I got stuck, I marked it and moved on. Planned to circle back, you know the drill. Made little notes on my scratch paper, trying to visualize concepts like the opponent-process theory of color vision. Yellow/blue, red/green… yeah, had to really picture that one.
This part took longer than I thought. I guess I forgot how much detailed recall is needed. Sensory adaptation, perceptual sets – these concepts sound simple, but the questions really test if you get them in different scenarios.

Checking and Reflecting
Finished the last question. Phew. Took a short break, grabbed some water. Then came the moment of truth – checking my answers. I went through it carefully, marking the ones I got wrong.
- Definitely stumbled on some specific details about psychoactive drugs and their effects. Need to review that section.
- Distinguishing between sensation and perception in tricky wording caught me off guard a couple of times.
- Sleep disorders? Got a few mixed up.
Seeing the wrong answers isn’t fun, but hey, that’s the whole point of practice, right? It wasn’t a disaster, but it clearly showed me where the gaps are. It’s one thing to read the textbook, totally another to apply it under pressure, even if it’s just self-imposed practice pressure.
Overall, it was a good session. A bit humbling, maybe, but necessary. Now I know exactly what parts of Unit 4 need more attention before I feel really solid on it. Just gotta keep plugging away at it. Practice really does make… well, better, anyway.
