Two half-free studentships shall be permissible instead of one free-studentship, but one-fourth free-studentships shall not be allowed. In awarding free-studentships the first consideration shall be the fitness of the candidates to benefit by instruction. Among candidates so qualified due regard shall be paid to poverty.
