高校入試対策　理科 is an Android application developed by SyuwaGakuin. It is a free educational program in the category of Education & Reference. The program is designed to help students prepare for the high school entrance exams in Japan.

The app consists of 572 practice questions covering the material from the first to third year of junior high school science. The questions include various formats commonly seen in high school entrance exams, such as multiple-choice, fill in the blanks, and short answer questions.

The entrance exam questions are known for having longer problem statements, which require strong reading comprehension skills. This app aims to improve practical problem-solving abilities by using actual entrance exam questions from public high schools in 2017.

The questions are divided into two categories: "Random," where questions from different topics are mixed together, and "By Field," where questions are grouped by specific topics. The "Random" category is particularly useful for testing practical skills across different areas. Additionally, the "By Field" category includes questions that require general knowledge of junior high school science, beyond just the specific topic.

The app also provides a feature to review and memorize the questions that were answered incorrectly. Users can revisit these questions and retake the tests until they achieve mastery.
