I am constantly struggling and not able to score in mocks more than 15 marks!

You got this! Instead of full-length mocks, try sectionals and take notes of concepts (quants). In varc work on your strategy. Give pyqs as mock instead of dashcat.

same here as well the only thing that im doing right now is to solve as many mocks as i can, cause we have less time time .do one thing at a time like if u focusing on quant do quant thoroughly dont go more into lrdi.

First, relax, take a break and reduce your tension, putting pressure on to exhausted mind will further reduce performance. Reduce the no of attempts to improve accuracy and avoid silly mistakes, and you will also have better visualization in Rc, di and quartz. Reduce your target syllabus and improve your command of them, you need only 40-50 per cent marks to achieve your goal.

thank you!
