Country : India | Demo Page You can familiarize yourself with the submission system for both paper mode and online mode on this link
http://logicmastersindia.com/2015/ISC_Demo/?online=1
This is repeated post, but if you are going to participate for the first time, we strongly advise you to visit the demo page and understand how it is working.
After the timing for ISC starts, the only thing you should be doing is solving the Sudokus, and not figure out how the website works.

Country : United States | For deficit surplus it's not clear what the rules are for areas with exactly 8 cells. Must the digits 1 - 8 appear or can we not operate under that assumption? In other words, are repeat digits in 8 cell areas forbidden? Thanks. |

Right, there is an ambiguity.
The rule should be "In regions with less than or equal to 8 cells, digits should not repeat" |

Yeah its very tough please someone provide any solving tips.
and about odd even view what are its basic solving strategy
Triomino (specifically Ashish's ) - Note exit points for corner boxes. If a triomino 'goes out' of the corner box, there needs to be another place where it 'comes in' to make up the numbers. So if there aren't two exit points, the box must contain the entire triomino within itself. As a general tip for this variant I suggest having two sets of markings, one for cells which will contain a Triomino, and the other for cells which must contain digits (which isn't necessarily limited to just the cells with givens/solved digits ).
Odd Even View - Where there are two clues, the rules force one of those clues to be in the first cell from that direction. If there is a side that is entirely double-clued like the example in the Instructions booklet, then whatever digit occurs only once (e.g. 8 ) needs to be in the first cell of that direction, since, using the first sentence, it can't be anywhere else. Also, as a general tip here, it is useful to have two sets of markings, one for 'cell containing odd digit' and another for 'cell containing even digit', these can be useful without placing a digit at all. For instance if you solve the IB one, you should get 2 in R9C1 which forces R7R8R9C3 to be odd and that can be marked to keep track.

Actually, generally speaking, all boxes must have 0, 2 or 3 exit points. No box can have 1 exit point. |

For a moment I thought it was the same puzzle as in the IB. The clues are positioned the same and there is also that pair of 1 and 4 on the left side : )
