First time demotivated by test

So there was this test named AIATS at my coaching. The Physics section was like hell. I mean me literally paper me skip kar kar ke dekh rha tha ki koi question karne layak mile. So this made me realise I suck at solving tough questions in limited time bcz abhi tak tests to easy-moderate se the, 250 score karta tha.. aisa challenge kabhi nahi mila ki marks 130 tak gir jaye (and yes, that shit's out of 360). Chemistry ka mai maan sakta hu ki meri galti h revise nahi kiya tha isliye thik nahi hua. Maths me bhi revision ki kami thi to tough chhodo, moderate questions bhi chhodne pade. But ironically Physics me hi lowest hain jiske liye mene sab dhang se revise kiya tha. So basically I *feel* like I need to practise those kind of *really tough* pathfinder level problems in Physics so I can atleast reach the level of solving them in the exam. But it maybe that I'm overthinking or smth. In contrast to the confidence boost you get after solving advance pyqs, jab actual hard questions se pehli baar encounter hota hai vo bhi exam me to dimag ka dahi ho jata h. I just need to ask, how do I level up in Physics? Which problem book should I use?
