State entrance exams may help you. According to government rule for MBA atleast 1 competitive exam scorecard is required for admission.

It's better to go for one more attempt, if you do not have more than 1 year of gap in your education. Prepare well for next year's MBA entrance exam. Keep practicing the questions of topics covered in CAT syllabus. Do join a good test series to evaluate your performance. Just keep a determined and regular practice towards preparation.

You need to write MAT exam for that. You can sit for MAT 4 times a year in the months of May, September, December and February. Please go to the MAT official website for the detailed information about MAT. Once the scores are out, you can apply to different colleges according to your score.
