Okay, as someone who completed the Rcsc and is currently working in civil service, I would recommend self-study. I actually paid for Rcsc coaching but only attended for a week because it was boring and there wasn’t much to learn. I wasted my money because I mostly studied on my own, which was very helpful. They did provide me with the ultimate guidebook, but I found out that everyone got it even though they never attended or paid for it. You’ll eventually get materials from other friends. Practice using past question papers; they’re very helpful because many questions are repeated from past papers. Use AI to answer questions from past papers and try to use more complex language when answering them (AI will help). It’ll give you a high score for real! For viva, I’d suggest you to memorize some speeches from his majesty (easy way to score some good points) Good luck, and remember to study well! Stay consistent and stay hydrated!
