I recently got selected for an MBA in lums.. I have also given CSS-2011..
The ideal situation for me would be to complete my mba and then join CSS(if i get selected)
However if i really have to choose, my priority would be CSS over LUMS mba. Thats why even though i hvnt yet cleared the CSS but i m willing to leave my mba if my css is in any jeopardy..

Now the thing is if i start going to LUMS, and (hopefully) if i also get called for the CSS interview.. i may not be able to take my days off for interview, psychological test, medical test etc during my studies..?? can that be a major problem for me?? if anybody has any insightful comments to share??

More importantly.. if i do get selected for CSS, then i think my joining will be around Jan of 2013, when my last semester of LUMS will start.. can i get some official delay for joining CSS if i m in the course of completing my Master's degree?????Please help..
