depnds if you are a subjective student my advise would be go for ltd work. go for smart work than hard work. well it works in my case.for law work on cases, costing and fm theory is a must. most importantly the material should be good enough to rely upon
good luck
there is only one tip for this and it is that you should concentrate on material given by our institute and do the hard work. smart work will do but if you want to secure rank you must to HARD WORK.
and REMEMBER there is no shortcut to success.
