Can I study for the HESI A2 in one week?

Only for the sections your school requires, as triage: diagnostic, A&P and vocabulary daily, math daily, sleep. If a required section is cold, a week rarely rebuilds it.

What should I do the night before the HESI A2?

Light review of your weakest required section, confirm your logistics, sleep normally. No new material.

If the diagnostic shows a big gap in a required section, ask your program: schools set HESI A2 retake policies and waiting periods. Confirm with your school and at evolve.elsevier.com.

Which sections will my school require?

It varies: commonly math, reading, vocabulary, grammar and A&P, sometimes biology or chemistry, occasionally physics. Your program’s admissions page or office is the only authoritative answer. The full section list is in our HESI A2 exam guide.

How to Study for the HESI A2 in 2 Weeks (2026)

Section structure per Elsevier’s HESI Admission Assessment · Required sections vary by program; confirm with your school

TL;DR. Two weeks is workable if you do one thing before anything else: confirm exactly which sections your school requires, because the HESI A2 is assembled per program and studying a section you won’t sit wastes days you don’t have. Then triage: anatomy & physiology and vocabulary first (the slowest to rebuild), math as a daily drill, grammar and reading for pacing; a diagnostic on day one, reviews at about 1, 3 and 7 days, one timed set, sleep. If the diagnostic shows big gaps in a required section, ask your school about rescheduling: retake rules and waiting periods are set by programs; confirm with your school and with Elsevier at evolve.elsevier.com.

Triage by section, after your school tells you which ones

Elsevier’s HESI Admission Assessment offers academic sections your program chooses from; most schools require four to six of them. (Confirm your list with your program.)

Section (if required)	Two-week priority	Why
Anatomy & Physiology	Days 1–4	The largest body of content to rebuild
Vocabulary & General Knowledge	Daily from day 1	Breadth you can’t cram in a weekend; short daily exposure wins
Mathematics	15 minutes daily	Conversions, ratios and dosage math fade fastest
Reading Comprehension	Days 7–8	Strategy and pacing; with no going back, careless first reads cost points
Grammar	Days 8–9	Rule drill, fast to refresh
Biology / Chemistry / Physics	Only if required	Check first; many programs don’t include all three

The 14-day plan

Day 1, confirm sections, then diagnostic. Questions in each required section before any review.
Days 1–9, largest and slowest first. A&P, then the rest in priority order; vocabulary and math as daily drills; every day opens with yesterday’s reviews.
Review spacing. Each item returns at about 1, 3 and 7 days, compressed to the calendar.
Days 10–13, mixed practice across your required sections, with one timed set. Practice committing to answers: the HESI A2 doesn’t let you go back.
Day 14: light review, no new material, sleep.

What wastes time

Studying sections your school doesn’t require: check the list first.
Rereading instead of answering: recognition, not recall.
All-nighters: sleep is when new material consolidates.
New material the night before, and long sessions on body systems you already know.

How Trelos does this

Trelos quizzes you before each lesson and skips the lesson when you get the questions right; what you got confidently wrong is re-taught first; and every concept comes back for review about 1, 3 and 7 days after you learn it — the same rhythm as the plan above. The HESI A2 track covers 180 questions across 30 concepts in six sections, and with full access you can start any section from the map, so your school’s required sections come first. The first topics are free with no sign-up to start. Full access is a $14 launch price through Nov 30, 2026 ($29 after): one payment, 12 months.

Pass guarantee: learn every concept in your track and keep up your scheduled reviews, and if you still don’t pass, your access is extended free — three more months per attempt — until you do. It’s an extension, not a refund.
