1600.io vs PeakSAT: SAT Math, Desmos and Pricing

See the 1600.io Premium membership (opens in a new tab) for current contents and renewal terms.

Inspect the Digital SAT Math Orange Book (opens in a new tab) if you need a systematic Math curriculum. Its Mastering Desmos course (opens in a new tab) addresses calculator techniques specifically. Video solutions can also help you review the reasoning behind a released practice question.

Premium includes multiple resources and older test material alongside Digital SAT content. Match the lesson and test version to the exam you will take; do not treat every older full test as a current adaptive practice test.

PeakSAT connects skill practice, lessons, flashcards, a saved daily plan and mistake review. Its Google AI question tutor offers a small hint or next reasoning step before an attempt; full explanations follow a submitted answer. Inspect the free worked examples and study tools before choosing full access.

Full Access costs $15 per week, $50 per month or $100 every three months, each recurring. Eligible first-time purchasers get a 7-day free trial with a card. Unless canceled before it ends, the selected plan begins charging. A saved practice workflow can support your routine; PeakSAT’s independent estimates are not official SAT scores. See current access terms.

Choose one Math topic you cannot yet solve independently. Work through the concept and one example, then close the solution and attempt a fresh problem. Explain the steps aloud. If Desmos was involved, check the requested quantity and verify the result algebraically where possible.

PeakSAT can help turn that topic into recurring practice and review tasks; 1600.io’s teaching may be the resource you use to understand it. Buying both is not necessary. Start with the missing part of your workflow and inspect free samples and official resources before committing.
