Follow this path to maximize your chances of passing on the first try
Start With Life and Physical ScienceYou are here
Open with the two biggest domains because together they make up 64% of the blueprint and carry the densest concept load.
Add Earth and Space Systems
Review tectonics, geologic time, atmosphere-ocean interactions, weather and climate, Earth motions, and astronomy so you can reason across systems rather than memorize isolated terms.
Tighten Inquiry and Engineering Skills
Practice variables, controls, graph interpretation, lab safety, measurement, and evidence-based conclusions because those skills can move points quickly in the smaller but high-leverage 11% domain.
Finish With Mixed Timed Sets
Simulate the 135-question, 150-minute pace and review misses by domain so the final week reflects both the ETS weighting and your actual weak spots.
Can You Take the Praxis General Science Exam?
Check if you meet the basic eligibility requirements
- •Passing scores are set by states and licensing agencies rather than by one universal ETS cutoff
- •ETS currently lists the live operational science exam under code 5436
- •ETS still offers an official practice product titled General Science: Content Knowledge (5435)
- •Current ETS availability PDFs list the exam as available daily
- •ETS currently lists at-home and test-center delivery where available
- •As of March 7, 2026, I did not find an official ETS notice announcing a nationwide blueprint redesign or replacement for the current General Science exam

Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
