If you can get recitation with him as well try to because he explains really well and if you ask him a question he makes sure you understand the concept. Very understanding, sweet, explains well and with examples. First time I went to class I was wondering if I made the right choice because I wasn't used to any accent, but it's so worth it don't make any quick judgements you'll understand him well after the first session. Good luck! - **2020-07** — Great instructor and easy course - **2020-07** — Patra is so sweet.

The problem is his accent, but don't worry, you will get used to it - **2020-07** — He's very sweet and nice but his explanation is not good. He gives raises though. ## See also - [All Chemistry courses at AUB](https://studiety.com/aub/subject/chemistry.md) - [Every AUB subject](https://studiety.com/aub/subjects.md) --- From Studiety (https://studiety.com/), an independent, student-run course guide.
