Mr. Hobart, the different requirement for F visa or X visa is that the Foreigner Medical Check, if you apply for F visa, it is not required, but it contradict the JW202, the best way is that you apply for X visa, it is only valid for 3 months and with XXX days stay in China, you can get the temporary residence permit within 30 days after entry under the help of your university. If you feel the level of study in the university is low, you can give up your study at any time. It won't effect your plan.
