Hello,

Yes you can appear for CLAT 2020 as you are in your 12th standard. While joining you have to show that you have successfully qualified 12th standard with good marks.

There is no other restriction to it. You can apply for it and prepare for it too. There is no maximum age limit so you can appear as many times you want untill you clear the paper and get an admission.

Hope it helps!
