In varc i attempt 3 rc and 4-5 va questions, with this strategy i was scoring around 25 marks but to increase my score i started doing 4 rc which resulted in less accuracy and reduced my score what should i do now to increase my score as I am stuck should I solve 4 rc or do 3 rc??

i would suggest to increase the number of VAs and continue with 3 RCs. But before that focus on accuracy of what you re already attempting. 25 marks is too less for the number of questions you are doing.

Selection of rc passages are important. Do 3 easy sets first and then move on to the the 4th one only if you think that the particular set is doable. Do not attempt RC sets which has lenghthy questions or tricky que as this can reduce your accuracy. focus on your accuracy and then increase the attempts.
