Studying abroad away from home can be more tiring than expected. Therefore, if you plan to study for more than 20 weeks, I recommend taking two courses.
For the first 8–12 weeks, you can focus on ESL to develop your overall English skills. After that, I recommend moving on to an IELTS or Business course.
The length of each course may vary depending on your English level, goals, and preferences, so please contact me for a more in-depth consultation.
