Rows: the real tone. Columns: what you answered. Red cells are your confusions; the drill plays your weak tones more often.
Same syllable, four tones
Pick a syllable and play the tones side by side. Listening to them back to back is the fastest way to lock in the shapes.
Telling the confusing pairs apart
2 vs 3
The big one. Tone 2 climbs steadily from the middle, like a surprised "huh?". Tone 3 drops to the lowest note you'll hear, often a bit creaky, and only rises at the end, if at all. Ask: did it go low first? Then it's 3.
1 vs 4
Both start high. Tone 1 stays up there, flat, like holding a sung note. Tone 4 crashes down fast and short, like an angry "No!".
1 vs 2
Tone 1 is level the whole time. Tone 2 is still moving upward when it ends.
3 in words
Before another syllable, tone 3 is a "half third": just low and flat, no rise (老师 lǎoshī sounds like low + high). Two 3rds in a row: the first becomes a 2 (你好 sounds like ní hǎo). Exams normally still expect the written tone 3.
Trick
Hum along with what you heard, or trace the shape with your hand. Your hand goes flat, up, down-then-up, or down.
