With a GMR of 42,000 in WBJEE and SC category, plus a TFW rank of 10,000, your chances for a TFW (Tuition Fee Waiver) seat are quite low because TFW seats are very limited (only 5% of total seats) and are usually taken up by much lower TFW ranks (generally within 3k–5k for popular branches in government and top private colleges). However, being SC category does improve your chances for getting a seat under reservation in government or private colleges through GMR, but the TFW quota is allotted strictly by TFW rank, not category rank. So realistically, you may not secure a TFW seat, but you should still get admission through SC quota in lower/mid-tier private engineering colleges in WB.

In west bengal 22% of seats are reserved for SC category candidates in wbjee so you have bright chance to get tfw seat with this rank.

To know the colleges you might get you can take help of TFW RANK CUTOFF where all the colleges opening and closing cutoff is given.

Good luck!!
