SAT question bank comparison
Dolphin SAT vs UWorld
Both Dolphin SAT and UWorld support mobile practice and mistake review. Choose by the access, explanations, and study routine you need, not an assumption that a question bank cannot guide daily study. Keep official College Board practice in your plan whichever provider you use.
Quick answer
Should I choose Dolphin SAT or UWorld?
Consider Dolphin for a free iOS starting point and a separate web practice and missed-question review workflow. Consider UWorld for configurable question-bank practice with explanations and planning tools. Try the relevant session before paying; neither a large question bank nor a guided routine guarantees a score increase.

How to decide
Step 1
Does UWorld also support guided daily practice?
Yes. UWorld describes a study planner, topic-focused quizzes and a progress dashboard, not only a bank for long, self-directed sessions. Dolphin also organizes practice and review around missed questions and skills. Compare what each tool tells you to do after a mistake rather than treating guided practice as an exclusive feature.
Step 2
What should I check in a missed-question review?
Use one missed or uncertain question as a trial of the review process. Can you explain why your original choice failed and why the correct choice works? Write down the skill or reasoning error, then solve a fresh question before rereading the explanation. A useful review session changes your next attempt; completing more questions without examining errors can leave the same gap in place.
Step 3
Is free access the same as a free trial?
No. Dolphin offers a free iOS starting point and public practice guides, while its web tools have separate paid access. UWorld advertises a seven-day trial, not ongoing free QBank access. Before subscribing, confirm the current duration, included subjects, cancellation terms and resources for the exact plan. Do not assume every app download includes every paid feature.
Step 4
Should I buy a question bank or a full course?
Start with the gap you want to address. If you understand the concept but need more attempts and feedback, question practice may be enough. If you need to learn the concept first, check the lessons included in your plan. UWorld distinguishes QBank access from a course with additional learning resources. Avoid buying overlapping subscriptions merely because one package has a larger feature list.
Step 5
Where do official Bluebook tests fit?
Neither provider replaces official College Board practice. Use a full-length Bluebook practice test to rehearse the digital format, then review the scored result and questions in My Practice. Choose targeted work between tests. Treat a third-party practice score as a separate estimate, not an interchangeable official result or a guarantee of your test-day score.
Step 6
How can I choose without paying for both?
Try a small practice set and a review session using the access available to you. Check whether the explanations address your specific errors and whether you can keep the routine on your usual device. Keep one primary routine if it already meets your needs; add another resource only for a clear gap. Record your error notes yourself rather than assuming progress transfers between different providers.

FAQ
Can I study for the SAT on a phone with UWorld?
Yes. UWorld describes mobile practice, explanations and progress synchronization through its College Prep app. Dolphin also offers a free iOS companion app. Check the access included with the specific app and plan you intend to use.
Is UWorld SAT practice free?
UWorld advertises a seven-day free trial. That is different from ongoing free access to its paid QBank or course. Check current trial inclusions and subscription terms before signing up.
Does a question bank help organize SAT study?
It can. UWorld describes planning, custom quizzes and progress tracking alongside its question bank. Evaluate the actual next-step guidance and explanations rather than assuming all question banks are unguided.
Should I still use official SAT practice tests?
Yes. Keep College Board Bluebook practice tests in your plan. Their scored results and question review in My Practice can guide the skills you work on between tests, whichever additional provider you choose.
