For those who haven't found it yet, I've built a completely free and highly accurate ATSA Preparation tool on 123ATC.

Here is what you can expect from this prep tool:

• It is 100% Free: No subscriptions, no paywalls, no hidden fees. You get full access to everything.
• The Most Accurate Prep Available: I've taken the ATSA myself multiple times, and I've worked obsessively with other test takers to ensure the mechanics, timing, and feel of these practice tests closely mirror the actual ATSA. The feedback from the most recent applicants confirms that this is the closest representation of the real exam available anywhere. There are many paid prep suites out there that are vaguely relevant and created by people without real test experience. This isn't one of those.
• Constantly Improving: I actively monitor feedback from this subreddit, the ATC hiring Discord server, and direct feedback from users. If something needs improvement, I make the updates rapidly.

If you want to dive straight into practicing specific sections, here are the direct links:

1. Memory / Differences
2. Value Assignments & Variables
3. Spatial / Visual Relationship
4. Radar Simulation / Collision Avoidance
5. Personality Assessment
6. Logical Reasoning & Reading Comprehension

Enjoy, and good luck!
