HI, 

in order to appear For RPVT 2019 . you need Mainly English , Physics ,  Chemistry and Biology  above 50% aggregate. So I dont think it would be a problem since you're clearing it in 2019. Also Application starts from march and exams are in JUne so you can apply for RPVT . You can also contact the examination department from their official website

Hope it helps, 

Good Luck.
