Questions are well but answers for the questions also provided then it is very easy to correction and checking
Answers are provided below
Dang..These questions don’t even require pen.
Guys try out advanced pyqs of isomerism..It’s literally worth it..
AIR 1 you gonna cop
Nice question for practices

Yes I also need
very nice questions
tha best
It’s good
I m in class 9 but still I can solve alll of the above questions
ikr
some what good but very less questions for online very basic but really good to increases your confidence soo
Very less questions available here for doing online questions
Good way to practice but do increase the level a bit … It is not comparable to jee main difficulty …
good ; useful but it’s somewhat low level
Exilent for clear a basic of isomerism question ✌💯🥳
good ;useful but it’s somewhat low level
low level bsdk? ab agar tu air 1 nai laya to dekh
This type of experience (combination of all papers in one topic)is very useful to preparation of jee.
Thanks for giving this type of experience.
