Are cracku Quant sectionals of cat level, because in mock i am not able to solve questions, but in sectionals i solve 7-8 questions

That's because when you give sectionals you are just focusing on one single 40 min section like if you are attempting QA section you're not drained after giving VARC and LRDI section like you do in mock so the difference you're feeling is because of you're not drained or stressed at all and all your energy is being utilized for giving one section with sheer focus and attention. Try to give a LRDI or VARC sectional just before QA in order to drain yourself a bit you'll see the difference. Cheers

I think both are almost cat level with dashcat quants a tad higher level

nice question
