hi,

see you did not mention which of the entrance test you have appeared in , generally there is percentage ratio of weightage to given both cet score and 12th exam score, for jee main exams 60:40 ration calculated for jee main score and 12th board exam score. now your cet score should be high since your board exam score is below 80 percentage to get a tier1 college, if you get more than 90% marks of total score in entrance test you have decent chances to secure a tier 1 college or government institute.
