Try to solve lower rated problems on greedy and basic math(till u reach 1100-1200) then binary search / prefix sum .

Try to solve as many problems as possible! To get to 1200, you should solve, A, B problems in a div.2, or A, B, C, D, E in a div.4. Also, don't stress too much about rating! As you solve harder problems, so will you rating increase with it. The main ideas you should know would be greedy, some VERY light number theory, constructive algorithms and binary search. For binary search you can do the EDU section on Codeforces, it is excellent.
