Dark dust settles on the surface of mountain glaciers every summer. Glaciologist Sanna Väisälä proposed that this dust speeds melting because dark surfaces absorb more sunlight than clean ice does. To test the idea, her team swept a set of marked squares on one glacier clean each morning and left neighboring squares untouched, measuring how much ice each square lost over the season.

Which result would most strongly support Väisälä's proposal?

Start with the free options

Before paying for anything, use Bluebook and Khan Academy. Bluebook is the official testing app, and its full-length practice tests are the closest thing to test day you can get. Khan Academy has free lessons and practice organized by skill.

Many students do well on free resources alone. You usually need something paid for one of two reasons: you ran out of full-length tests, or you need far more practice questions on a few weak skills than the free options give you.

Paid options by price (September 2026)

R.test: about $15 to $19 a month. LearnQ: from about $59 a year. StudyPebble: $19.99 a month or $129 a year. UWorld: about $149 for 90 days or $249 for a year. Princeton Review self-paced: about $299 a year. PrepScholar: about $397 a year. Acely: about $49 to $149 a month depending on the plan.

These are list prices from each company's site in September 2026 and they change, especially around test dates. Check before you buy, and look for a free trial so you can see the questions first.

What actually matters when you compare

Question quality comes first. Do the questions look and feel like the digital SAT: short passages, one question each, the same kinds of answer choices? Try ten free questions before you pay.

Next, full-length tests. The digital SAT is adaptive: your first module decides your second. An app whose full tests don't route the second module can't give you a realistic score.

Then explanations. Every miss is only useful if you understand why the right answer is right. And finally price over your real timeline. Most students prep for 2 to 4 months, so a yearly plan only makes sense if it's cheaper than the months you'll actually use.

Where StudyPebble fits

StudyPebble's full-length practice test is free, adaptive between modules, and built from original questions in the real topic mix. Practice mode has written explanations on every question, tracks the skills you keep missing, and saves them to a mistake bank to retry. The free plan includes 5 practice questions a day. Pro removes the limit.

It's built for students who've used up the official tests or need a lot of targeted practice. If you only need a few more full-length tests, the free test may be all you need.

Questions students ask

What is the best free SAT prep?

Start with Bluebook for official full-length tests and Khan Academy for lessons. Add StudyPebble's free adaptive practice test when you run out of official tests.

Is paid SAT prep worth it?

It's worth it if free resources have run out for you: no fresh full tests left, or not enough practice on your weak skills. Otherwise free resources can carry you a long way.

Is a yearly plan better than monthly?

Only if you'll use it for enough months. For StudyPebble, $129 a year is cheaper than about 6 and a half months at $19.99. Most students prep for 2 to 4 months.
