i took before ikoma and bunka before. bunka u need alot of self revision to maintain the pace. not a easy task i must say. ikoma also need to do self revision, but not so extreme, pace is slower. both for its own pros and con, u want learn quick, u got self disicpline, most worth it is to go bunka. if you wanna learn at steady pace, abit lazy type of person i suggest for ikoma. i find both of them focus on conversation pretty well. my friend who took from (i forget the school name, its those 1 year intake once or something like thatt one, dam famous school also), he told me conversation practices not much there. he say one lah i dont know
