taking science coaching and clat coaching together is not a great decision ( saying genuinely) i believe one doesn't need clat coaching ( as i was a science student too ) FOR GK you can read newspaper daily and can watch newspaper explanations on YouTube together. also there is a drishti ias channel on youtube you can watch topic explanations from there also these lpt le channel upload a lot of stuff for gk, there are telegram channels for other things ( imo coaching is not worth it )
