# NTUST Course Predator

- Type: Project
- Year: 2019



I built this bot because I was frustrated with missing out on university courses due to a manual, luck-based registration system. As a beginner, I wanted to take control of the situation and **automate the tedious task** of refreshing pages and clicking buttons. This project was a major turning point for me; it proved I could **solve my own problems through code**, giving me the confidence to focus on self-driven learning rather than comparing myself to others.

I started with **Selenium** to simulate clicks but soon integrated **OCR (Pytesseract)** to bypass captchas with **80% accuracy**. To make the system more robust, I added status checks that saved **95% of my monitoring time**. In the final version, I replaced the browser simulation with **HTTP requests**, which optimized the tool to save over **500MB of RAM**. Successfully securing my seat with this bot is what sparked my passion for building practical, efficient software.
