Starting from scratch as an adult is tough because school basics fade so fast, and just watching videos usually doesn't give you the structure you need. When I was trying to rebuild my confidence with technical English for data analysis, I kept hitting a wall with the heavy math terminology. I actually started using https://edubrain.ai/calculus-homework-helper/ to guide me through complex problem-solving in English. Even though it's a math assistance platform, explaining limits and derivatives with their tutors forced me to practice specific vocabulary and logical phrasing in a real-world context. Finding a niche topic you enjoy and discussing it with experts is honestly a great hack to boost your language skills.
