GIBS looks at entrance exam scores in a very simple and balanced way. They don't judge you only by your CAT/MAT/XAT/CMAT score — they just use it to check your basic aptitude.
Even if your score is average, it's totally fine because GIBS focuses more on your overall profile, your confidence, and how you perform in GD & PI. These exams just help them understand your basics in quant, reasoning, and verbal, but the final selection is more about your attitude and willingness to learn.
So, scores matter, but they're not everything — GIBS gives everyone a fair chance.
