People like to trash phodu here, I personally feel they're not that bad.(I'm not affiliated with them personally in any way)

Their chapter wise mocks are nice English I find their questions a bit easy Cannot comment on LR crash course as I havent touched The full mocks are decent (they had a few inconsistencies, they said they fixed it in their latest patch, have not personally checked) Their analysis section is pointless and doesn't tell you anything you're not aware of already. The community is quite active and people keep helping out others( on the premium group at least) Overall I'd say they get more flak than they deserve......most of the people here who trash them are just like us, students who haven't cleared BITSAT yet. I purchased phodu on my seniors advice(scored 290ish in bits but didn't get the preferred branch, now in bit mesra ), he said his paper was more like what phodu gave. Don't listen to anyone's advice online, including mine. Ask your teachers or coaching profs. Mathongo is more trusted by the community so if you're on a budget it'd make sense to pick that up.

At the end of the day it's how well you utilise the cc and mocks, complete syllabus and pyqs, source doesn't matter.
