from ur education point of u first of all u decide weather u want 1)simply degree
or 2)degree with sufficient aggregate if u choose first one so aim for getting passing marks..select some easy units to read, refer some previous year question papers
and practice some test papers thats all!!
but if u choose the second one prepare a time table for each of them. if u r sa slow learner then take up some of the units to clear in the current sem..and u can opt for rest in the coming sem. but our advice to u is to complete all of them at single shot only to reduce ur workload at the end..some people got year back’s also ! so better dont neglect them. it is easy to clear them coz u already prepared fo them before.all the best!
