Feeling lost affecting PGEE prep
GATE 2021: 1700 rank GATE 2022: 3500 rank this has broken me. a year full of preparation and results not at all as expected. I am preparing for PGEE but I feel lost. I want to get into IIIT H but I am not currently confident enough. ... and IIIts like Allahabad. My expectations are much higher and PGEE can solve all my problems for now. how should I deal with this?
