Hi

Yes, you are eligible for cuet entrance examination even if you have got  70% marks in 10th examination.

This is because,
Marks or percentage obtained by you in class 10th is not taken in account to consider eligibility for CU ET i. e Christ University Entrance Test, only your class 12th qualification is taken in account for the purpose of checking whether you are eligible or not.

For example,
CUET B.Tech Eligibility Criteria is provided below for your reference :-

-) you should be either appearing for your 12th board examination or  should have passed it with 50% marks in aggregate of Physics, Chemistry, Mathematics , and also 50 % individually in maths in 12th.

You can take the same at our page the link is provided below

Similarly,
for the rest of the programs offered by CUET  like BBA BCom etc , your 10th marks or percentage is not considered so you don't need to worry, focus on your 12th board examination.

And now that you are in 12th and will be appearing for your board examination soon, you are eligible for CUET 2021 entrance examination as an appearing candidate

Thank you
