有谱-爱学习（数理化） app for iPhone and iPad

Youpu currently provides full support for 3 junior high school subjects: mathematics, physics, Chemistry, and mathematics of senior high school, mathematics of primary school. It subdivides the entire knowledge structure into more than 2000 knowledge nodes. With over 150,000 carefully designed practice questions, Youpu supports over dozens of textbooks versions; helps you efficiently pinpoint knowledge weaknesses; and simplifies your learning and revision process. There’s no need for cramming and endless exercises! Your scores are easily improved with Youpu!

What troubles students and their parents the most is usually that they “Can’t find what the problem is”! Therefore, they always have to review from scratch, and usually end up doing needless work

Youpu is specially designed to help you solve this key problem. Once you figure out what you do not understand, you are half way from solving the problem. With the problem becoming clear, you can focus all your energy to solve it, and naturally your efforts become more efficient. Even for those who are still in need of tutoring, time and cost efficiency is still achieved.

Youpu subdivides the entire knowledge structure into more than 2000 knowledge nodes(16 times the number of chapters; and 8 times the number of sessions in text books). With the use of the highly efficient adaptive testing mechanism and Big Data application, accompanied by high quality test questions, your status at each knowledge node is precisely categorized as “Excellent” with colour green (three stars), “Good” with colour blue (two stars), “Medium” with colour yellow (one star), “Poor” with colour red (no star) and “Unknown” with colour gray. You rank among your peers is also clearly visible, both nationally and locally within your test region.

Moreover, it would not require too much time from you! With 5-10 minutes per subject per day, the fragments of time you spend on Youpu allow us to clearly map your complete cognitive diagram.

Youpu discovers your learning status in real time, and helps you predict your perspective scores and rankings in the coming monthly/unit, midterm/final exams, and high school entrance exam.
