Essential app for the CSAT for the most efficient practice mock exam study
To ensure your efforts are not wasted due to variables in the exam room, boost your practical CSAT sense with Realism. 📝 CSAT Simulation Take practice mock exams while listening to the sound of the bell—which you will hear in the actual exam room—along with white noise. In Realism, you can maximize your practical sense through various randomly played noises and an analog clock screen. 🔊 Random Noise Playback Practice while listening to randomly played sounds such as coughing, chair noises, and sighs. By adjusting the difficulty level while practicing, you can experience the "sandbag effect" of the actual CSAT exam room. ⏰ Analog Clock Since the CSAT only allows the use of analog clocks, you must prepare by thinking, "It's 9:30," rather than "There are 30 minutes left." In Realism, you can view the exam time for each subject on the analog clock at any time. ⏱️ Lap Time Function While solving problems during the exam, press the Lap Time button to easily check which questions you spent the most time on and whether your time allocation went according to plan. 📊 Mock Exam Recording and Statistics Function After practicing with mock exams, record your scores and feedback, and use the statistics function to track changes in your skills at a glance. Easily manage your score trends by subject, average scores, and number of attempts. 📴 Offline Mode You can use all simulation features even in environments such as academies where internet access is unavailable or access to websites is restricted. You can also partially use the feedback writing and viewing functions.
