It is a university where monks and laypeople study together. There are many branches in other provinces and the main branch is in Ayutthaya. I just hold a student visa and apply to study for a bachelor's or master's degree at that university. And when the visa is about to expire, the university will issue a certificate to confirm that you are actually studying here. We just hold that certificate and residence permit to extend our visa for 1 year. and report every 3 months. That is, there are regular classes (cheap tuition) and classes only on Saturdays and Sundays (but the tuition is expensive). For me, I studied English for 4 years (regular ) and spent only 45k Baht on tuition. I currently have a bachelor's degree. But I continued my studies one more degree and waited for my time. Hopefully next year I'll go to Paris.
