Hello, I'm just concerned about my upcoming upgrade test. Previously I've given an OA containing the 4 problems. Questions were too tough, I managed to solve the medium one, But wasn't able to do the easy one, which seemed pretty hard. Even cannot touch the hard and complex problems.

This Time I prepared hard, Still it feels like I'm not able to reach those questions (Very Very Hard DP Problems as I recall). Can someone give any pattern or preparation strategy that would be helpful for Hard and Complex level questions?

Time is short, But I'm ready to work hard. I don't want to mess up again like the previous one (Where the Easy Problem Gets Hard when Testcases not passed, Preparing for Hard level might give me some option and hope).
