How did you find Broga Hill? Easy, Good, Hard or Very Hard? (non stop climb to 4th peak). If you find its 'Hard' then you have to work harder.
Agree with few above comment. You need to prepare your strong mind to overcome some obstacles and good stamina too. Don't worry for short train period, you still got 2 month to train. Good luck to you.

Don't forget climb Gunung Tahan to test out your progress.
