OMG! Exams are knocking my door, With the pressure of studying more and more. There is only some time left, And I haven't prepared anything yet. I won't be able to sleep I bet. My answers are weird, And the doubts are not cleared. The notes are to be revised, Games and fun have to be sacrificed. On my table books are piled, And when I see them, I go wild. Only work and no play, What a difficult life I must say!!
Try not to use acronyms like that. Poems should be...flowing and elegant. I know, my vocabulary needs a makeover. But I do like it! Much better than your stories, dare I say. But you might be trying a little too hard to rhyme. Don't push the poem into rhyming; if there's something that goes better with the poem but doesn't rhyme, put it in anyways.
The rhymes oft seem kinda forced. Once again, you need to work on your sequencing - only put in a rhyme if it fits, because there are tons of different types of rhyme and rhyme scheme. You don't have to force a perfect rhyme if you can easily fit a near rhyme or an elided rhyme. Don't jump around from subject to subject.
Also, tone and emotion are important in poetry. And your wording doesn't really have enough of an impact. Be clever in your use of simile and metaphor - use big words, strong words. Words like 'OMG!' reallyt bog down the poem.
Also, this poem doesn't really have meter or flow to it. You need to have an established meter for the poem to feel natural, and the syllable count is very erratic, leading to a disjointed feel.
For future reference, make sure to rhythmically read the poem in your head to check for meter.
