Thanks CAMBA. Any knows honw to apply for TA or RA in Purdue? Do we need to appy seperately? Remember "Xiao Niu" mentioned that some Chinese students got TA/RA with tuition waiver which are really enticing, =).
Pls bear NYWEN's comment in mind. Also to my understanding you do not really need to specifically "apply" for the TA or RA. The ADCOM will judge by your application material and grant the TA or RA or scholarship. For TA and/or RA they will also send you invitation for interview. (not for the admission itself but for the position of TA or RA)
