Khan Academy: concept study
Use the SAT preparation linked by College Board to work on concepts and skills. It is a free starting point when you need to learn the reasoning behind a question.
See the Khan Academy guide →Student Question Bank: targeted items
Use College Board’s question bank when you want official questions for focused practice. Bring a specific skill target and leave time to review the explanations.

Compare a study workflow, not a feature count
Choose the outcome for this session
Decide whether you need a baseline, instruction, targeted practice, or review. More features do not automatically help with the task in front of you.
Try the full loop
Enter through the normal app navigation, attempt a question, inspect the explanation, and find the question again. Note any friction that would stop you doing this regularly.
Keep the smallest useful toolkit
Choose tools with distinct roles. If two products do the same job, compare cost and actual use. Avoid switching tools so often that you lose track of your mistakes.
A working checklist
Before choosing a combination
Use this during your session. These checkmarks are a temporary worksheet and are not saved to your Dolphin progress.

Common questions
Why are these not ranked from one to four?
They serve different purposes, and this guide does not have comparative learner-outcome evidence to justify a universal ranking. Match the tool to the task and test whether it helps you complete that task.
Are all four mobile apps?
No. This guide compares digital study tools, including a testing app, websites, and Dolphin’s product. Check each provider’s device requirements for the version you intend to use.
