How These Tools Help Students Study Smarter
Track Writing Progress with the Word Counter
Whether you are writing a college application essay (650-word limit), a research paper, or a blog post, the word counter gives you instant feedback on word count, characters, sentences, paragraphs, reading time, and keyword density. It uses the same whitespace-based counting method as Microsoft Word and Google Docs.
Calculate Your GPA Accurately
The GPA calculator handles both unweighted (standard 4.0) and weighted (honors/AP) GPA across unlimited courses. Add your courses, select letter grades, enter credit hours, and review an estimated semester or cumulative GPA. Useful for scholarship applications, college admissions, and academic planning.
Structure Focused Work with a Pomodoro Timer
The Pomodoro Technique is commonly used as a simple structure for alternating focused work with short breaks. Try different intervals and keep the pattern that fits your task and energy. Our Pomodoro timer includes customizable intervals, session tracking, and browser notifications.
Know Exactly What You Need on Your Final
The grade percentage calculator removes the guesswork from end-of-semester planning. Enter your current grade, the weight of your final exam, and your target grade — and it tells you exactly what score you need. It also includes a weighted grade calculator and a full letter grade to GPA conversion table. Pair it with our guide on building a study schedule for a complete strategy.
