Since I used a different book, it seems I unlocked some unexpected luck~

Chemistry.
20 grand!

Maths.
Yeah, this one kills me as always. Seven questions.

Physics.
Fifteen! ( •_•)

Of course, I had to do a lot of picking, because this book - unlike, or maybe just like - the last one has the next year's portions involved. But the difficulty level is almost half. If I needed to use four concepts to solve one question in the other book, I need just two here.

But my self-esteem in solving questions still remains crushed. :')
