I tried everything at some point
DAMS F2F (2nd year): few good teachers, but app interface is bad, QBank weak, offline model not for me. Rarely used it.
PrepLadder (3rd/Final year): Solid teachers
Marrow (Internship): The QBank + GT platform.
Anki: 75% of my prep
There are more atoms in a grain of sand than there are grains of sand on earth.
Hold a grain of sand and you hold a paradox: more atoms inside it than grains of sand on Earth. Each atom holds nuclei with quarks, gluons, quantum fields flickering from the void.
Infinity nested in the finite. The cosmos hides in your palm disguised as dust.

Why does matter feel solid when atoms are 99.9999% empty space? If a nucleus were a marble, the atom would be a stadium. Electrons don’t orbit like planets. They exist as quantum clouds. They repel other electrons via electromagnetic force, and the Pauli exclusion principle forbids any two electrons from occupying the same state. This combo creates intense resistance when atoms get too close. So what you feel as “touch” is actually the electromagnetic and quantum pushback of trillions of electron clouds refusing to overlap.
