Perhaps you should try some spelling variations:
hoc nganh » hoc nhanh
khung hoc » nhung hoc, thuong hoc, trung hoc
chung hoc » trung hoc, dung hoc, hung hoa
anh hoc » sinh hoc, benh hoc, hinh hoc
cuu mon » cuu mo, cuu mot, cuu cong
mon hoc » toan hoc, dong hoc
hoi cac » hoc cac, voi cac, hoa cac
cac van » cac dan
van tai » von tai, van tuan
tu anh » tu hanh, tu manh, thu anh

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu anh hoc tap, nghien cuu mon hoc nganh ((khung hoc) OR (chung hoc)) xa hoi cac van tai~.
• Adding a wildcard symbol may retrieve word variants: tu anh hoc tap, nghien cuu mon hoc nganh ((khung hoc) or (chung hoc)) xa hoi cac van tai*.
