Note- On an emotional note, we end our Prelims 60 Days plan 🙁
It was a great experience with all of you. The love and support received was truly overwhelming. We will not call it a mix response since it was an amazing one 🙂 Every single day was full of new learning for our Team as well as for you (we hope). We might have sounded harsh sometimes for which we apologize. We also apologize for few unattended queries. Our special apology for Hindi medium aspirants since we couldn’t manage timely disposal due to paucity of resources. We tried our best but nothing is perfect so as WE. There is always a scope of improvement in everything. We intend to learn from our mistakes and will try to get over all these in our future initiatives.
Some of you have given us enough emotional attachment and learning experiences that we are forced to mention- Anuj, Sepoy, Nishant, Pushpendra, Akhil, Anshika, Raman, Baba ka Bhakt, krishna koundinya, Anand, Nikhil Joshi, Biman Ghosh, legaleagle, Draconian, Dark Knight, L.I, Nick Will, Ab, Lee Min, Aditi, malli babu, Bilal, pr39048 to name few . Pardon for not mentioning others as they are in our memory because of continuous interactions 🙂
