I don't play very much on KGS anymore; however, I played this game and really enjoyed it. I made a few obvious mistakes that I noticed, but I think it deserves a review. Oh unfortunately, I couldn't finish this game due to time since I had a Calc class I needed to attend.

Maybe your calc teacher can explain about 1 hour = 60 minutes and so on? I used to do so when my students arrived late.

Re: Defeated by the time limit
Proverb: vital points before large points. Making a base for an unsettled group is vital, not merely large.
Up to move 25, B has a nice attack going, but W has compensating profit. B has a large investment in the three stones on the left, so it is important to keep them strong and efficient. Playing an extension to make a base for this group sometime soon (before W can counter-attack) is critical.
strikes me as an overplay. You cannot surround these W stones, much less kill them, so this seems like a good time to switch to a vital extension on the left side like C6 or D6. If W cuts at K13, you have the tesuji sequence L13-K14-K15-L14-L15 to escape.
defends the K13 cut and threatens a large hane at L16, but allows W to switch to the left side, which looks more important.
is huge, making a base for W and depriving B of a base. Vital points like this are much larger than may appear at first glance. The three B stones on the left are suddenly floating and have lost all attacking and territorial prospects.
is again big, but not as vital as 
. Now B will have to struggle just to live here, letting W consolidate a large corner territory in the process.
There were some mistakes in the fighting after this, but the real problem was getting into this situation in the first place.

Re: Defeated by the time limit
Sure b has plenty internal threats but in the end position wF11 makes the left side ko, no?
