Hey Anku! Yes you can attempt for it in 2020 if you cleared your 10 + 2 in 2019. You can go for JEE Advance two consecutive times only. JEE Main is the eligibility test for appearing in JEE Advanced examination. JEE Advanced 2019 is a national-level entrance exam conducted for providing admissions in the engineering programs in IITs. The seven zonal IITs conduct the exam under the guidance of Joint Admission Board (JAB) for admission into Bachelor’s, Integrated Masters and Dual Degree programs for all the IITs. 

Hello aspirant !

Let me to inform you that you can give the jee mains examinations for three times only.  And the jee advance for 2 times.  In all total you first need to qualify in jee mains .Since once you have given jee mains now you have two attempts left then yes in those two attempts if you qualify you get Chance to give jee advance 2 times. One more thing if you were passed board exam in 2018 then you can't be able to appear in JEE advanced 2020.

All the best!!

If you have cleared your JEE advance one time then there is no need to appear for the second time for the advance. And the advance can only be given if you have cleared your mains. If you have appeared in 2019 and you have cleared your advanced then you can directly get the admission or else you have to give next time for the IITs.
