is GATE for mtech a good idea in this market ?

Has anyone taken the pw gate course for DA for gate2026. thinking of buying it , is it worth it at all ? or should i stick to free online resources as per the syllabus . Iam a 3rd year engineering student not sure if i should pursue masters at all.but just thought of giving an attempt as im already doing data science skills like maths probabilty ai/ml , databases, etc.
