<P> Sometimes the ENEM replaces the old elimination Part I ("primeira fase") of the Vestibular . Alternatively, ENEM results may be used as part of the final overall grade in the Vestibular . More rarely, a few public universities have decided not to use ENEM grades at all and continue to base their admission criteria on the Vestibular only . Notable examples in the latter group include the highly prestigious federal military schools like ITA and IME and, as of 2010, the prestigious state research universities in the state of São Paulo (USP and UNICAMP). Resistance to the ENEM among some top public universities comes mostly from the perception that the national federal exam is less selective / rigorous than the older independent Vestibular . </P> <P> Another important recent development in university admissions in Brazil has been the introduction in most federal universities of a quota system where a certain number of places are reserved a priori to applicants of a certain racial / ethnic background who have completed their pre-university studies in a public (i.e. state - funded) school . Candidates who qualify may apply to a course of interest under the quota system either through the national SISU system or directly at their university of choice (in case that university uses both its independent Vestibular and the national ENEM exam to select applicants). Again as a notable exception, the selective federal military schools and the state universities in São Paulo have so far refused to use any quota system based on race or schooling background . USP and UNICAMP, however, have instituted a race - blind "social inclusion program" that gives a bonus in the final Vestibular mgrade to candidates who come from the public secondary schools, thus boosting their chances of securing a place in certain university courses of interest without necessarily using a pre-determined quota . </P> <P> In Canada, students applying from high school generally hear word back from a college or university between late March and late May, though offers of admission may be extended to high achievers (through GPA or other submissions) as early as November--January . Internationals / US applicants are likely to receive an offer or rejection by early April, depending on the original submission of documents . In some cases, an institution may offer admission in a high schoolers Grade 11 year, if monetary fees are sent in early . </P> <P> Many Canadian universities offer dual admission to students upon completion of their graduation requirements . </P>

In which process are students limited to applying to only one college or university
