I feel bad for not studying-

I was in the top 10% of my year level last year and lo and behold the first batch of tests come out and I'm absolutely burnt out. I don't have the energy nor motivation to study, how am I ever going to conplete VCE?

I know what has to be done to be successful I want to be successful. But I just can't convince myself to get up off my ass-

I have 4 days busy days until my General Maths test and 6 until my Bio test.

Do I have enough time to get up to my usual standard? Can I cram a whole topic into my brain?

Any tips to study in a short time would be great.

Specifically: General maths, measurement - area and perimeter (3D shapes and all that shit)

Biology: DNA, mutations, cell division, natural selection, RNA (and other stuff of the like)

I know there are people ahead and I used to top my science class. Is it possible to catch up in a week or so? I mean it's only one topic right?
