I made it to DSE without a coaching. Here's my strategy.
I had received a few DMs on how to prepare for CUET PG COQP10 (Economics). So instead to replying individually to everyone, I thought I'd make this post.
Resources - For Micro and macro, I'd suggest following HL Ahuja for the theory part. Pindyck and Hal Varian for some mathematical part. In Macro, you can follow Blanchard or Froyen. Any standard undergraduate textbook is more than enough. Also, class 11 and class 12th books are also helpful for MCQs. I'd suggest mapping topics from PYQs and then studying them from each of the notebook. Use AI to organize your notes. Sydaester & Hammond for Mathematics and NG Das for Statistics. For Indian Economy, I'd go with direct PYQs and then mapping the topics and further makes notes using AI. Econometrics part isn't really extensive and can be done with college notes or simply watching one shot youtube videos.
Strategy - Structure your preparation in 70:30 ratio of syllabus completion and PYQs/practice questions in the early months. As you get closer to syllabus completion, start giving more weightage to solving PYQs and Mocks. I'd suggest you purchase practice mocks and test papers from an online coaching like Arthapoint. You don't need a complete course, but solving good quality mocks are non-negotiable to crack CUET PG. Make extensive and smart use of free trials of AI platforms like ChatGPT, Gemini, etc. Use them to make practice questions, analyse the syllabus and study question patterns. Learn how to prompt and make effective custom chatbots. This skill will go a long way in your career. Focus on completing Microeconomics first, since concepts from Micro are frequently used in other subjects.
Online Help - I don't really have a particular suggestion since there are a ton of economics based youtube channels but Arthapoint's DSE question series is a godsent. I used to watch it daily during the last two months of my preparation. It gave me idea of the breadth of the questions that might come in the exam. Other than youtube, you should definitely consider investing in a good quality mock test package. For that, you can go with Arthapoint or Edusure. I found Arthapoint's mocks more challenging and fleshed out. I found others to be too easy and not really a good example of how CUET PG asks questions.
Final Remarks - Be consistent, focus on understanding the concepts rather than forcing stuff inside your brain. That won't help in the long run. You need to learn the application of concepts, not brute force it. All the best.
