Assessment Prep,
Built Around the Student.
International schools · Level tests · US & UK exams
The same exam still calls for different practice depending on a student's grade, current level, and target score. Blossom Books doesn't choose a workbook by the exam name alone — we build the right study plan around the student's current level and purpose, with a detailed answer key in every title.

Assessments we prepare for
Start with what you're preparing for
Not an international-exam-only shop. We support three preparation goals equally — academy and school placement tests, international-school and grade-level academics, and standardized exams.
International School & Academic Prep
For students in — or preparing for — international schools, and for US/UK curriculum learning.
English · Math · Science · Reading
Placement & Level Test Prep
For academy and school placement, streaming, and level checks — built around grade and current reading level.
Reading · Vocabulary · Grammar · Writing · Math
Standardized Test Prep
For MAP, CAT4, SSAT, ISEE, UKiset, SAT, AP, GRE, LSAT — aligned to each exam's skill areas and question types.
Reading · Writing · Math · Reasoning
We turn the problems we see in class into the problems in the workbook.
Our materials are built by educators who studied in the US and have taught students of many levels. We watch where students get stuck, which explanations click, and where difficulty jumps — then design the questions and answer keys around it.
Teach
We teach students directly.
Observe
We spot recurring mistakes and weak skills.
Analyze
We analyze feedback from real prep teaching.
Design
We design question types and difficulty.
Review
We re-check answers, explanations, and level.
We teach. We observe. We build.

See difficulty in the questions, not just in words
The same reading skill, shown across three Blossom Levels — so you can tell which one fits your child.
What is the main idea of the passage?
Find the central idea stated in the text.
Which statement best summarizes the whole passage?
Summarize and synthesize several details.
Which inference is best supported by the author's argument?
Infer what is not stated, using evidence.
Frequently asked questions
Are the questions similar to the actual test?
We analyze each exam's skill areas, question types, and grade-level scope, and build practice around them. We do not provide real or leaked exam questions, and we avoid claims like “100% identical.”
Does difficulty differ by grade?
Yes. Difficulty is built around the student's grade and target level; some titles progress from Foundation up to Advanced or Challenge.
How do I choose between 40 / 60 / 100 pages?
It depends on how much time is left and current ability. 40P for a quick check, 60P for standard prep, 100P for intensive repetition. Our team can help you pick.
Is an answer key included? Is it in Korean?
Yes — every title ships with a detailed answer key. International-school, level-test and US-curriculum titles include Korean explanations; SAT/AP and professional exams are explained in English with key points in Korean.
How is it delivered?
As a digital PDF by email after payment is confirmed. You can print it and study on any device.
Can you make a title you don't list?
Yes. We produce custom workbooks to a student's grade, level and target exam. Ask us through our official channel.
