A user in a Reddit post asked which topics he should skip for GATE CSE 2027. As per experts, it is recommended that for GATE CSE 2027, you should completely skip officially removed networking topics (like ARP, DHCP, and ICMP) and NP-completeness proofs. Additionally, save time by skipping complex pointer implementation mechanics for AVL or B-Trees and advanced code optimization in Compilers, focusing instead on their high-yield mathematical and conceptual properties.
