All of the above sentences mean you will pass or fail by a small amount.
By the skin of your teeth is used when something is positive but only just
e.g. I was late for my train, but I caught it on time by the skin of my teeth.
A cat's whisker is very thin - it means a small amount
e.g. I was a cat's whisker away from winning the race. - it means you only just, by a small amount, lost the race.
It could go either way - this means you are in the middle and you could succeed or you could fail because you are very close to both.
e.g At 80 minutes the football match could go either way and there is no clear winner.
I hope this helps

Explanation: If something is in the lap of the gods, it means that you have no idea which way it will go. In other words, it could go one way or the other. In any case, nothing you can do now will change the end result. In terms of an exam, this expression would mean that you have a 50/50 chance of passing in your opinion.
Example sentence:
"Whether John passes or fails is now in the lap of the gods."
解説：もしも誰かが神の膝に乗っている in the lap of the gods 場合、その人は次に何が起こるか全然予測できないという意味になります。別の表現ですと、どちらにも成り得るということです。どちらにしても、あなたが何をしても結果を変えることはできません。試験でいうなら五分五分の確率で合格すると考えるということです。
例文：
"Whether John passes or fails is now in the lap of the gods."
（ジョンが合格するかどうかは今や神のみぞしることだね。）
"Too close to call" describes a resulting that could go either way. For example, political elections sometimes are too close to call, until the official results are published. This expression comes from sports, where call has signified “a judgment” since the mid-1600s.
"Too close to call" という表現は、「結果がどらにも転がる可能性がある」ということを表します。
"Political elections sometimes are too close to call, until the official results are published.
（政治選挙は実際に結果が発表されるまでどうなるかわかりません。）
この"Too close to call"というフレーズは、スポーツで"call"="a judgment"（判定）として1600年代半ばから使われるようになったことが由来です。
I am on the edge of passing or failing this class.
I am on the border of passing or failing this class.
Here we can either use the words, "edge," or, "border," to explain that very close to either passing or failing something interchangeably to mean the same thing.
