Dear Aspirant

Hope you are doing well

Now let me go through your question

Yes it is good for you doing mock test series but  do practice previous year paper and take care of time management and small tricks which help to consume less time and boost your accuracy of answer

And if you want you can try knockout test preparations visit link https://learn.careers360.com/knockoutfull-jee-main-april/?icn=jee-main-knockout-lpage&ici=search-section_c360-home

Hope it helps

Thank you
