辞职全职复习还是兼职业余复习？

本人，IT企业普通员工，工作很紧张，前些日子该企业的一名员工据说就是被累死的。

如果不加班，每天到家一般要在7：20左右，然后吃完饭怎么也得到8：45左右了。9点开始复习，只能复习2.5个小时，而且因为白天太累了，效率也不是很高。

如果加班，一般要10点左右才能到家。基本复习不了什么了。

现在研究生毕业已经一年有余，已然大龄青年，深感时间紧迫。希望早一点把GMAT拿下。

但是，辞职回家全职复习，又有点难以割舍，毕竟现在工作也不是这么好找。

恳请过来人指点一二，至谢！

It's your call.  This is only the start.  Think about what you will do when you have to face a million different things during MBA (quit some?).  Think about what you will do when you finish your MBA and have to take care of a family as well as perform well in your job.  Not to mention that you will need to explain the professional experience gap on your MBA application. 

Thanks for your instruction. But I really think if I can't complete two thing at the same time, I have to learn to give one up. Don't you think so？

p.s. I have been working at this company after my graduation

Ok, simple logic here.  MBA is for advancing your career.  With that, comes more and more juggling acts.  You can't keep dropping the balls or a MBA will be pointless.  This is where you can practice and learn how to multitask.

If you can't work out a test and a job now, how would you learn to deal with an application and a job later?  After that, how would you split your time between recruiting events, interesting talks, and school work?  Once you graduate, how would you handle increasing work load and responsibilities (assuming you do well) and heavier family demands?

I meant that you will have to explain to the school about you not having a job from now on (if you do quit).
