They’re available 24/7 on Chegg’s online platform, making it easy to start learning or get some extra help ASAP. You can search through thousands of homework problems on the Chegg platform or upload a photo and ask an expert for help with a specific question.

A subscription for Chegg Study costs $15.95 a month and includes access to select textbook solutions, video walkthroughs and practice sets, and its experts. Those in need of a little extra help can also subscribe to Chegg Writing ($9.95 a month), which provides users the ability to scan papers for plagiarism, create automatic citations, and receive expert writing help at any time. There's also Chegg Math Solver, which gives users unlimited solutions and detailed explanations for tough problems, as well as access to a graphing calculator, for $9.95 a month.

While online tutoring programs can be invaluable for many students looking to achieve their learning goals, they’re often pricey and unattainable for many families. The nonprofit Learn To Be aims to bridge that gap with a "choose if you can pay" model for its one-on-one online tutoring in a digital classroom.

The company's tutors have served more than 7,000 students since the nonprofit launched in 2012. The program offers math, science, reading, and English tutoring to students in kindergarten through 12th grade from qualified families. Parents regularly report that their children’s test scores and GPAs improved significantly after enrolling in Learn To Be.

If your family needs affordable tutoring, head to Learn To Be’s website to fill out an enrollment form. If you’re approved, your child will be matched with a tutor by email, and they will create a personalized study plan from there.

Princeton Review is one of the most comprehensive online tutoring services on the market. The company's tutors—who are available online 24/7—offer homework help and live learning sessions for everyone from kindergarteners to adult learners in more than 250 subject areas.

Subjects include math, science, history, drama, and the humanities (taught in both English and Spanish), as well as ACT, SAT, P/SAT, and GED test prep, AP and IB courses, student success skills (like note-taking, organization, and time management), nursing and health, business, technology, essay and cover letter writing, and even career support.

Princeton Review's prices depend on the package you choose. If you subscribe on a month-to-month basis, prices range from about $40 for an hour of tutoring (usually broken up into three 20-minute sessions) to roughly $115 for three hours of tutoring. Packages range from around $350 for 10 hours of tutoring across six months to about $1,450 for 50 hours of tutoring across six months.

Princeton Review also offers free tutoring for students from U.S. military families, funded through the U.S. Department of Defense and Coast Guard Mutual Assistance.

Preply, one of the best online tutoring services for language learners, boasts thousands of native-speaking tutors from about 185 countries around the world. Students can use Preply to grow their working vocabulary, complete foreign language homework assignments, or even work toward becoming fluent in one of dozens of languages.

Each Preply language tutor sets their own prices and schedule, so you can search for them by availability, nationality, language, or cost. After scheduling a first session that fits both your and your tutor’s schedule, you’ll meet with your new tutor to discuss your goals and take your first lesson.

You can also browse language tutors’ profiles to read reviews from other parents and students to make sure you find the best fit for your child. Students who aren’t satisfied with their first session can try another Preply tutor for free or receive a full refund.

Costs vary depending on the tutor and frequency of sessions, but the average is around $18.30 per hour.

A flexible pay-as-you-go learning model—around $1 per minute, with a minimum of 15 minutes in one sitting—makes Skooli one of the best online tutoring services for instant homework help.

You or your child can ask a specific question or start chatting with a tutor to see if you get along. Within seconds, you can begin a live video session from any device with a tutor who specializes in popular subjects like trigonometry, calculus, chemistry, or physics. Skooli’s interface is also uniquely interactive, with a virtual whiteboard that allows students to work through tricky problems alongside their tutor.

Skooli offers tutoring help for elementary, middle school, high school, and college students in math, science, languages, the humanities, and business. Students can rewatch their tutoring sessions anytime to jog their memory about what they learned.

Pearson’s Smarthinking is one of the best online tutoring services available for students who want to improve their writing skills.

Although Smarthinking’s tutors—90% of whom have master’s degrees or PhDs in their chosen subject—can teach middle school, high school, and college students in almost any area of expertise, they truly shine when it comes to helping learners achieve their potential in writing. They can improve academic and career writing, and even help you brush up on grammar and APA style.

Smarthinking’s prices are also reasonable, especially considering the tutors’ level of expertise. Four hours of on-demand, online tutoring in your choice of over 150 subjects costs about $150, while an hour costs roughly $45.

You can also submit your or your child’s sample SAT or a school essay assignment for a comprehensive review by an expert writing tutor. Fees for this service range from around $13 for an SAT essay to approximately $32 for a standard-length essay and around $50 for an essay over 10 pages long.

For older students looking to land a job or start college, Smarthinking’s resume, college admissions essay, and cover letter review services could help them reach their goals.
