UCAS by universities and are either unconditional or conditional, where the latter means that the student will receive a place dependent on exam performance. Applicants also find out if they have been rejected through UCAS Track. Once an applicant has received a reply from their choices, they must reply to their university before the deadline in May. Applicants normally choose two offers through UCAS, one as their firm choice and one as their insurance choice. A firm choice means that, if the student receives their grades required, then the student will receive an unconditional offer. An insurance choice means that, if
Virtually fibered conjecture fact, given that the geometrization conjecture is now settled, the only case needed to be proven for the virtually fibered conjecture is that of hyperbolic 3-manifolds. The original interest in the virtually fibered conjecture (as well as its weaker cousins, such as the virtually Haken conjecture) stemmed from the fact that any of these conjectures, combined with Thurston's hyperbolization theorem, would imply the geometrization conjecture. However, in practice all known attacks on the "virtual" conjecture take geometrization as a hypothesis, and rely on the geometric and group-theoretic properties of hyperbolic 3-manifolds. The virtually fibered conjecture was not actually conjectured by
