Sure, but start right now solving a few problems from previous years.

You'll want to know how to open and read a file, parse input (generally line by line, splitting each line on spaces), get familiar with data structures such as the dictionary/hash map and how to use the OCaml version. Not that you'll be competing for the leaderboard; this is more about getting familiar with the typical things for solving each problem.
