How to Make Spare Time Practice More Effective?

While apps offer convenient access to practice, without a structured plan, it's easy to fall into the trap of "ineffective fragmentation." Here are some expert-backed strategies:

  • Set Clear Goals: If you're preparing for a job interview, focus on Keraft's business interview scenarios and HelloTalk's professional language exchanges. If you're targeting an English exam, prioritize exam-focused apps paired with Keraft's simulated test conversations.
  • Track Progress: Use apps with built-in progress trackers, like Keraft's CEFR-aligned score dashboard, which updates with a line chart, 4-dimensional radar, and heat map of weak areas after each practice. This helps you identify what to focus on next.
  • Spaced Repetition: > Based on classic psychology research covering hundreds of experiments, spaced repetition helps with long-term memory retention. Review your corrected sentences and new vocabulary from Keraft and other apps at regular intervals to reinforce what you've learned.
