Actually the NCERT books are sufficient to crack the JKCET but nowadays the competition is increasing year by year so As my suggestion is considered please refer the some of the reference books for Physics, Chemistry, Mathematics and also slove the previous year question papers and as well as sample question papers and also memorize the formulae and please watch the NPTL videos for the important concepts in the Physics, chemistry, mathematics and also follow the perfect time management make sure that concepts are Revisied too many times so that you are able to give your best in the JKCET for sure for further any more information please refer this careers360 link
