can i improve rc score in one month. i am getting around 10

yes you can but dont keep unrealistic expectations from 10 you can move to around 24 in cat if you go frenzy with quant prep just focus on geometry,arithmetic(most imp),alegbra.....atleast have a good grip on the previous years questions concept asked in cat from these topics

My score is a little inconsistent, varying in the range of 25 to 40, I would suggest to try different ways to attempt. Don't aim at attempting the entire section at one go. If you're comfortable with VA, don't miss out on any of those questions and attempt 2 RCs. With 8 questions of RCs, given you get 6 correct, you bag 16 marks. Moving on to VA, do not skip the TITA questions. Try and get 6 questions correct again, minimum, that's another (best case scenario you get only TITA wrong), you bag another 18. That's 34 in total. Try this, maybe it helps.

i used to score 60-70-75s in mocks and suddenly i am hitting 40s from my last 5 attempts, how to avoid silly mistakes in quant?

Get better pleb, Dont make silly mistakes

Not scoring good in varc sectionals, can someone guide me for a good accuracy at RCs, and let me know if sectionals are at par with actual cat or not?

These RCs are on tougher side obviously to make you prepare for the worst. To have a good accuracy i would suggest read Aeon essays and after reading make questions by yourself and also write a summary of the same.

I found these Cracku mocks irrelevant they are unnecessarily making quants a lot tougher. Is there anyone who feels so?

idk i found them pretty good level, bro check slot 3 last year

yes ...its actually tougher than the actual cat

i am struggling with RC . i always choose the wrong option. what's wrong ?what to do ?

Been there. Done that. I will suggest using option elimination. First, look for extreme options and eliminate them. Next, remove options containing alien information. Once you eliminate at least 2 options every time for a couple of mocks you will get the hang of it. Good Luck!!!
