Unlike tutor marketplaces or casual speaking platforms, E2 uses a standardized system with guided modules covering each skill area—Reading, Listening, Writing, and Speaking. Students can track their progress, identify weak areas, and receive targeted support based on their score goals.

Pricing:
E2 offers tiered plans:

Basic (Free): Access to practice questions and some videos

It’s also ideal for self-disciplined learners who prefer a professional framework rather than casual tutoring.

We recommend using E2 Test Prep for core exam skills (grammar, strategy, timing) and combining it with speaking practice platforms like Cambly or Preply to ensure performance under real-time pressure.

Pros: Professional curriculum, structured by exam, great video content, live teacher sessions
Cons: Less personalized than one-on-one tutoring, requires self-motivation

2. Preply – Flexible One-on-One Coaching for Exam Success

Preply is a versatile online tutoring marketplace that allows learners to find expert teachers for personalized exam preparation. Whether you’re aiming for IELTS, TOEFL, TOEIC, or Cambridge exams, Preply enables you to choose a tutor who specializes in your target test and customize your study plan.

Unlike fixed curriculum platforms, Preply gives you total control: you can filter tutors by exam type, pricing, native language, teaching style, availability, and ratings. Many tutors offer mock speaking interviews, essay writing reviews, and exam strategy coaching, making the experience highly exam-relevant and student-specific.

Preply is especially helpful for learners who need direct speaking and writing feedback in a private setting. Whether you’re preparing for IELTS Speaking Part 2 or TOEFL integrated tasks, you can practice with live feedback and repeat drills until you’re confident.

Pricing:
Tutors on Preply set their own rates. For exam preparation, expect:

$10–20/hour: Emerging tutors or those from lower-cost regions

We recommend Preply to those who have taken the test before and are looking to raise their score by 1–2 bands, or to learners combining general study apps with tutor-guided corrections. It’s also useful for professionals preparing for English-speaking interviews or certification renewals.

Pros: Personalized attention, flexible schedule, wide range of tutor pricing, targeted skill improvement
Cons: No fixed curriculum, tutor quality varies, requires time to find the best match

3. Cambly – Real-Time Speaking Practice for Exam Fluency

Cambly is best known for providing instant access to native English-speaking tutors around the clock—and it offers a dedicated service for learners preparing for high-stakes exams like IELTS and TOEFL. While Cambly doesn’t follow a strict exam curriculum, it excels in helping students improve speaking fluency, pronunciation, and confidence—the exact skills needed for high performance on speaking tests.

Many Cambly tutors are familiar with IELTS and TOEFL speaking rubrics, and you can find teachers who specialize in mock interviews and performance coaching. Lessons can be tailored around expected questions, time limits, and feedback loops to simulate the real test environment.

The platform is perfect for test-takers who struggle with spontaneous answers, filler words, or pronunciation clarity. Cambly also allows lesson recordings, enabling students to review their speaking performance and track improvements over time.

Pricing:
Cambly pricing depends on lesson duration, frequency, and billing cycle:

30 min × 2 days/week: ~$65/month

Students preparing to study abroad or attend interviews in English can use Cambly to sharpen their delivery, control nerves, and learn how to sound natural under pressure. Combine it with structured prep from platforms like E2 Test Prep for a full-scope strategy.

We often suggest using Magoosh as the foundation of your prep plan, then transitioning to platforms like Preply or Cambly for test simulation and oral feedback in the final stage.

Choosing the best platform for English exam preparation depends on your goals, study habits, and budget. Whether you’re aiming for IELTS Band 7+, a TOEFL scholarship score, or simply trying to pass an academic placement test, each service we’ve reviewed offers a unique advantage.

Use E2 Test Prep if you want a structured, test-specific curriculum with video lessons, mock exams, and scoring tools.

Cambly is ideal for learners who want to boost speaking confidence and fluency under real-time pressure.
