How skill practice differs from a full test
Practising the SAT by question type is the fastest way to fix a specific weakness: instead of sitting a full 98-question test, you pick one or a few of the 30 Digital SAT skills, draw questions you have never seen or got wrong before, and work through 10–15 of them with instant feedback on each. No timer, no score conversion, just understanding why you missed what you missed.
A full practice test answers "where am I now": timed like the real exam, scored on the 400–1600 scale, tracked over time. But it is a poor tool for repairing one specific gap. Of 98 questions only a handful belong to the type you struggle with, and they are scattered among questions you already handle well.
Skill practice works the other way round. You choose the exact type you need, say Transitions or Right triangles & trigonometry, and see only questions of that type. Each answer is checked immediately and the explanation appears at once, so every question is a correction rather than an exam. Once the type holds up, go back to a full test to confirm it.
30 Digital SAT question types in 8 domains
The list below follows the College Board framework. Every question in the Bluebook Vietnam bank is tagged with one type, so choosing a type means practising exactly that type, and your mastery per type is computed on the same list.

How to build a practice set
- Pick a subject. Reading & Writing or Math. The list of question types changes with the subject.
- Pick question types. Select one or several. The dot next to each type is your mastery: red is where to start, green is solid, grey means not enough data yet.
- Choose where questions come from. Questions you have never attempted to broaden, questions you got wrong to fix old mistakes, or questions you bookmarked while taking a test.
- Set the size and start. 10–15 questions suits one session. Each answer shows right/wrong and the explanation immediately; the set is saved to your account to continue or review later.
What the free tier includes
A free account sees all 30 types with its own mastery, can select any of them, and can build 3 practice sets in total. This allowance is separate from the 3 free practice tests; building a set does not use up a test.
Explanations on the free tier are previews: you see what the question asks and how many steps the solution takes, not the full working. Full explanations, Vietnamese versions where available and the AI tutor are part of the paid plans.
Frequently asked questions about skill practice
Is skill practice timed, and does it give a 1600-scale score?
No. This is study mode, not test mode: there is no clock, no conversion to the 400–1600 scale, and results do not enter your score chart. To find out your current score, take a full practice test.
Can I practise by skill before taking any practice test?
Yes. The "Never attempted" source draws from the whole bank and needs no history. Mastery dots stay grey until you have answered enough questions of that type.
What does the coloured dot next to each type mean?
It is your accuracy on that type, computed from every question you have answered on the platform: green is solid, amber needs work, red is weak, grey means too few answers to judge. It is the same figure as the skill map on your My Learning page.
How many questions should a set have?
10–15 for one session, enough to notice a repeated mistake without tiring. If the types you chose do not have enough questions left under your filters, the builder tells you the real number instead of silently returning a shorter set.
Do I see the explanation right after answering?
Yes. Each question is checked as soon as you answer and the explanation appears below it; answered questions are then locked. The free tier sees a preview of the explanation, paid plans see the full version plus the AI tutor for follow-up questions.
How many practice sets are free? Do they count against the 3 free tests?
3 practice sets in total, counted separately from the 3 free practice tests. The limit is checked only when a set is created: a set you have created can always be finished.
How is this different from practising a single test section?
Section practice runs one whole module of a test, timed, and is part of the paid plans. Skill practice is individual questions grouped by skill, untimed, available on the free account too. One trains stamina and pacing, the other repairs specific gaps.
