The HiSET is a fast-growing alternative to the GED that's accepted nationwide, but most test-takers underestimate how much preparation they actually need. Unlike cramming for a single subject test, passing HiSET requires a structured timeline and realistic understanding of its difficulty level. This guide breaks down what you need to know before hiring a tutor or enrolling in prep courses.
What Is the HiSET and How Does It Differ from the GED?
The HiSET (High School Equivalency Test) measures the same competencies as the GED—reading, writing, math, science, and social studies—but uses different question formats and slightly different content emphasis. While both are nationally recognized, HiSET tends to have more straightforward language in reading passages and slightly less dense math problems. The test is offered by ETS (Educational Testing Service) and costs around $140–$160 depending on your state, compared to the GED's typical $120–$130 per subject.
One key difference: you can take all five HiSET subtests in a single day if you choose, whereas many states require GED testing to be spread across multiple sessions. This flexibility appeals to test-takers who want to get it done quickly, but it also means scheduling intensive prep becomes crucial.
Understanding HiSET Difficulty
HiSET difficulty is often rated as slightly easier than GED, particularly in mathematics and reading comprehension. The average passing score is 8 out of 20 on each subtest, and most states accept this minimum. However, "passing" doesn't guarantee success in college or career—many employers and colleges prefer scores of 12 or higher.
The math section demands algebra and basic geometry understanding but rarely ventures into advanced calculus-style problems. Reading passages are drawn from workplace, academic, and literary texts, typically at grades 9–12 level. Science and social studies questions focus on reading and interpreting data rather than memorizing facts, which actually works in your favor if you can develop strong comprehension skills.
Realistic Timeline for Test Prep
Your prep timeline depends entirely on your starting point. Here's what typically works:
- If you're a strong high school graduate: 4–6 weeks of focused study, 10–15 hours per week
- If you didn't finish high school but have some recent academic experience: 8–12 weeks, 15–20 hours per week
- If it's been 10+ years since high school: 12–20 weeks, 20–30 hours per week
- If you struggle with reading or math fundamentals: 16–24 weeks with intensive tutoring support
Most successful test-takers spend 100–150 total study hours before sitting for the exam. Cramming for just two weeks almost never works; your brain needs time to retain material across multiple practice cycles.
Choosing Between Self-Study, Online Courses, and Tutoring
Self-study costs $20–$60 for prep books and free resources (Khan Academy, official HiSET practice tests). It works if you're disciplined, but most people need structure.
Online prep courses run $100–$500 and include video lessons, practice questions, and progress tracking. Platforms like Kaplan, Coursera, and GED.com all offer HiSET-specific modules. You get guidance without the expense of one-on-one help.
In-person or online tutoring costs $30–$80 per hour. A tutor identifies your specific weak spots—maybe you can't factor polynomials or summarize science articles—and targets those gaps. Most test-takers benefit from 10–20 tutoring hours combined with independent practice.
When hiring a tutor or service, confirm they specialize in HiSET (not just GED). Ask whether they use official ETS practice materials and can provide sample lesson plans. Mercoly helps you compare and find trusted GED & HiSET Prep providers in one place, making it easier to vet credentials and pricing upfront.
Practice Tests Are Non-Negotiable
Take at least three full-length official HiSET practice tests under timed conditions before test day. The first one shows your baseline; the second one, taken after 4–6 weeks of study, shows your growth; the third one, one week before testing, confirms you're ready.
Official practice tests are available free on the ETS website. Avoid relying solely on third-party practice questions—they often don't match the real test's difficulty or question style.
Frequently Asked Questions
Q: Can I retake the HiSET if I fail a subtest? Yes, you can retake individual subtests, and most states allow unlimited retakes (though some charge a fee per retake, typically $20–$40 per subtest). This makes HiSET more flexible than some other high school equivalency exams.
Q: How long does my HiSET certificate last? Your HiSET certificate never expires. Once you pass, it's valid forever for employment, college applications, and credential purposes.
Q: Is tutoring worth the money if I'm on a tight budget? If you struggle with one or two subjects, 5–10 tutoring hours focused on those areas often costs less than retaking the entire test multiple times. Consider it a strategic investment rather than an all-or-nothing expense.
