If I changed to soft power such as education in a local university in Bangkok, but I couldn't confirm to stay for 6 months now.

Though there're 9 levels to complete the whole course, each level only lasts about 6 weeks and different levels can be done on different dates throughout the year as long as there're sufficient people in the class.

At the moment, I couldn't confirm is the course really suitable for me or not, hence I've paid for 1 level and booked a hotel for 3 months stay.

I'll consider to apply for the next level only after finishing the first level.

So if I changed my application to soft power, can I just provide 3 months stay in a hotel instead of renting an apartment for 6 months?
