have a question about some punctuation for 'though' and 'even though':<br/><br/>"He applied to Havard (<span style="color:#ff0000;"><b>,</b></span>) <i>even though</i> he had no chance of admission."<br/>"He applied to Havard (<span style="color:#ff0000;"><b>,</b></span>) <i>though</i> he had no chance of admission."<br/><br/>I think that comma is optional before 'even though', but is mandatory before 'though'. Am I wrong?
