Sharpen – College Exam Prep

Review by eFreeware

Sharpen is a college exam preparation app from McGraw-Hill Global Education, the textbook publisher, and it is free to download on Android. It sits somewhere between a study planner and a question bank: you take quizzes, work through flashcards and short videos, and the app uses what you do to point you toward the topics that need more attention.

That combination is the main reason to consider it. Most study apps ask you to bring your own material and organize it yourself. Sharpen starts from content the publisher has already written and aligned to its textbooks, then layers study recommendations on top. If your course uses a McGraw Hill title, the app is built to match what you are already reading.

It has been downloaded more than 100,000 times and holds a 4.3 average from 939 ratings, which suggests a reasonable level of satisfaction among the students who have tried it. The app is free, though it does offer in-app purchases.

Quizzing yourself the way the exam will ask

The quiz bank is the core of the app and the part most students will spend their time in. The basic mode reads as a warm-up, advanced pushes into harder material, and exam mode is meant to feel closer to the real thing.

The question formats vary more than a typical multiple-choice drill. There are standard multiple choice questions, single-choice questions, fill-in-the-blank items and multiple-choice questions that include images. That variety matters for subjects where a diagram, a chart or a labeled figure is part of the assessment, and it keeps a long practice session from feeling repetitive.

There is also a built-in timer for simulating exam conditions. Working under a clock is a different skill from knowing the material, and having the option to practice with time pressure is a sensible inclusion for anyone preparing for a timed final.

The quiz bank draws on thousands of questions, according to the developer, spanning the disciplines the app covers. That range is the practical benefit: instead of hunting for practice questions chapter by chapter, you work through a set that has already been matched to the textbook.

Short-form study between longer sessions

Not every study session is a two-hour block, and Sharpen leans into that with several shorter formats. Bite-sized videos explain key concepts in a compact form, flashcards cover key terms from the textbook, and visual chapter summaries condense a chapter into something you can review quickly.

The step-by-step practice problems are the most substantial of these. Rather than just telling you whether an answer was right, they walk through the reasoning, which is useful when you are learning a method for the first time and need to see how a problem is actually worked. For quantitative subjects like accounting, algebra, chemistry or business math, that format is likely to be more valuable than a plain answer key.

These formats work well together as a rotation. You can watch a short video on a concept, run through flashcards on the terminology, then attempt practice problems before moving to the quiz bank. None of it requires a long sitting, which is the point of the design.

Ask Sharpen and the Improve insights

The two newest pieces of the app are Ask Sharpen and Improve, and they are where the study experience becomes more personalized. Ask Sharpen lets you enter a query and get a deeper explanation of a topic, along with links to related study activities and newly generated learning content built around what you asked.

That is a different approach from browsing a fixed catalog of lessons. If a lecture left you confused about one specific idea, you can go straight at it rather than working through a chapter from the beginning. The developer describes the feature as an AI study companion, which is a fair way to frame what it is doing.

Improve takes the opposite direction and looks back at what you have already done. It uses past sessions to show your strengths, flag knowledge gaps and recommend what to study next. The value of a feature like this depends on how much you use the app, since the recommendations are only as good as the history behind them. For a student who quizzes regularly through a term, the picture it builds should be more useful than it would be after one session the night before a final.

Together the two features cover both directions: Ask Sharpen for the question you have right now, Improve for the pattern across weeks of work.

What you need before the content lines up

Sharpen is built around textbooks, and that shapes how you get started. The content is aligned to McGraw Hill textbooks and OpenStax textbooks, and the material is written by McGraw Hill subject matter experts. The closer your course sits to one of those titles, the more directly the quizzes, flashcards and summaries will map onto your reading.

The disciplines covered include accounting, algebra, American government, American history, anatomy and physiology, biology, business, business law, business math, chemistry, economics, engineering, human resources, investments, management, marketing, medical assisting, medical terminology, microbiology, music, nutrition, psychology and Spanish, among others. That is a broad spread across the introductory college catalog, and it points to the app being designed for general education and lower-division courses rather than specialized upper-level work.

The app is free to download, and it does offer in-app purchases. There is nothing in the way of a complicated setup to describe here: you install it, and the work of matching it to your course is mostly about whether your textbook is one of the supported titles. The app was released in October 2022 and was last updated in October 2026, with the most recent changes described as improvements to the experience and bug fixes.

Students who will get the most from it

The clearest fit is a college student in an introductory course that assigns a McGraw Hill or OpenStax textbook. In that situation the alignment does real work: the quiz questions, term lists and chapter summaries correspond to the chapters you are being tested on, so practice time goes toward the right material without you having to build a study set from scratch.

It also suits students who study in fragments rather than long blocks. The mix of short videos, flashcards, practice problems and quizzes means a fifteen-minute gap between classes can be spent productively, and the Improve feature rewards that kind of regular use by tracking where you are weak over time.

Students preparing for a timed exam will find the exam mode and timer worth using, particularly in subjects where pacing is part of the challenge. And anyone who tends to get stuck on a single confusing concept has a direct route to an explanation through Ask Sharpen rather than paging back through a chapter.

The app is rated for Everyone 10+ and covers a wide range of introductory subjects, so it works as a general study companion across a semester rather than something tied to one course.

A study companion worth trying if your textbook matches

Sharpen makes the most sense as a term-long companion rather than a last-minute rescue. The features that distinguish it, the personalized recommendations and the gap analysis, need a history of quiz sessions to say anything useful. Used regularly alongside a course, that is where the app should earn its place in a study routine.

The quiz bank, the range of question formats and the timer give it enough substance to stand on its own as exam practice, and the shorter formats fill in the gaps around it.

It is free, and the in-app purchases are there if you want them. For a student in a supported introductory course who wants structured, textbook-matched practice with some guidance about where to focus, Sharpen is a reasonable app to install and use through the semester.
