Waiting for articleship calls

Hello, there could be ,multiple reasons as to why you have not received any calls yet. Usually the ideal time to apply for articleships is a couple of days before the results are announced(in case of big firms) and also immediately on knowing the results. The practice varies from firm to firm. Few firms complete the recruitment process a month or so before the results and ask the candidates to join after the results.

First of all review your resume to check whether it is in the proper format and whether you have supplied  all required information in it

Secondly, I think youmight have to visit the firms personally and deliver the resume...because the database of some good fimrs will be loaded with firms submitted online, 

If you have contacts in any of the firms try to send your resume through them. All the Best :)
