Most of these past challenges have made the time requirement extend 1 week beyond the last needed armor. This is the first event where they have made the time crunch so tight by making the reward earnable only during the same week as the final armor. Some think this is a mistake on Gree's part, and that they will extend the deadline later, while others think this is a way for Gree to squeeze a little more money out of the players.

Though this is a little late, my advice (assuming you are strong enough to reach lvl 43 by day 4) is to accumulate crafted 1* armors (most likely snakeskin) until 66 of you 70 armor slots are full. Once your armor finishes, level it to about 20 using nothing but basic armors. Though more costly (about 150k gold give or take) this saves your more valuable armors for the higher levels and only takes a couple hours to accomplish.

After hitting level 20, switch and start using your 1* armors to level further. This should get you to lvl 30 or 33 depending on how many armors you could hold. At this point, a single fusion boost (if time is more valuable then gold) or combine 4 armors with fusion stones (cost about 100k to do) and use those to enhance (make volcanic mantle = 50 EP * 4 = 200 EP) it to 35.

There will be some variation in this strategy, but it should get you to lvl 35 within a few hours and for a somewhat reasonable cost.
