hello

if you had prepared from ncert then it won't be a big deal for you to crack upsee as jee mains which is considered to be tougher than upsee asks all of it's questions from ncert. the chemistry syllabus of upsee can be found at https://engineering.careers360.com/articles/upsee-syllabus. here all the chapters are from ncert so you can expect most of the questions to be from ncert.

hope it helps.
