How long does it take you to solve them in practice? Of course if it's longer than 2 hours then you won't solve them in contest. If you can solve them quickly in practice but not contest then it's probably nerves and you can try some virtual contests. Otherwise, what tends to take the longest when you solve? Coming up with the logic? Implementation? Debugging WA/RE?
