Hi aspirant,

You have not mention the name of any examination or college so it is very difficult to answer your query. In general the admission to lateral entry programs are done on merit basis based upon your performance in diploma while some colleges conduct their own entrance examination for the same. Now the academic session for any course ends in March or April so who can expect the admission to begin by the end of April but it completely depends upon the institution you are talking about.
