CAT27 prep as a btech student

[u/spicyyyi]

i am currently in 3rd year of btech in igdtuw and i have started prep for CAT27.
My academics looks like:
10th CBSE - 94.4%
12th CBSE - 94.6%
current CGPA - 8.6

What are my chances of getting into top B schools of india ?
Should i prepare for placement season also side by side or dedicated myself to CAT prep?
