Day four of the ICC Under-19 World Cup in the United Arab Emirates saw the tournament's first big upset as Afghanistan beat Australia by 36 runs while Bangladesh, India and Pakistan also won.
India, who beat Scotland by five wickets and Bangladesh, who beat Namibia, have qualified for the quarter-finals.
Pakistan, beaten by India in their opening match, got off the mark with a win over Papua New Guinea.
Scotland were dismissed for just 88 by India but almost staged a remarkable fightback. Andrew Umeed scored exactly half of their runs with 44 but they had no answer to India's bowling, led by Aamir Gani and Kuldeep Yadav, who both took four for 28.
Yadav's haul included a hat-trick when he dismissed Nick Farrar, Kyle Stirling and Alex Baum with the final two balls of the 19th over and the first of the 21st.
India then slipped to 22 for five in reply as Chayank Gosain took three for 31 only for Sarfaraz Khan to hit an unbeaten 45 and Deepak Hooda 24 not out to steer them to victory in 22.3 overs.
India 4 points, NRR 1.783 (qualified for quarter-finals)
Pakistan 2 points, NRR 1.050
Scotland 2 points, NRR -0.273
Papua New Guinea 0 points, NRR -2.473
Pakistan thrashed Papua New Guinea by 145 runs to take their first win of the tournament. Man-of-the-match Imam-ul-Haq struck 88 and Sami Aslam 62 as Pakistan posted 283 for eight in their 50 overs.
Kiplin Doriga then hit 51 for PNG before they were bowled out for 138 in 29.2 overs. Zafar Gohar took four for 35 and Zia-ul-Haq two for 26.
An outstanding performance from Afghanistan has left Australia needing to win their final game against already-qualified Bangladesh if they are to progress.
The Afghans were bowled out for 253 with Mohammad Mujtuba (75), Ihsanullah (63) and Hashmatullah Shaihi (57) all making half-centuries.
Three wickets apiece for Cameron Valente and James Bazley kept Australia's target under control but they failed to make it.
Bazley was left unbeaten on 54 as they were dismissed for 217 in reply. Jaron Morgan (47), Jake Doran (45) and Damien Mortimer (43) all made useful contributions but they weren't enough.
Abdullah Adil and Sharufuddin Asif shared seven wickets to clinch a memorable victory for Afghanistan.
Bangladesh deservedly won through to the quarter-finals with a second comprehensive win in as many matches, beating Namibia by 52 runs.
Bangladesh 4 points, NRR 0.924 (qualified for quarter-finals)
Australia 2 points, NRR 0.650
Afghanistan 2 points, NRR -0.031
Namibia 0 points, NRR -1.530
Mosaddek Hossain continued his strong form with 70 not out and Shadnam Islam made 65 as Bangladesh posted 233 for five batting first.
Xander Pitchers made 40 for Namibia and Gerhard Erasmus 37 before their challenge faded and they were all out for 181 in 49 overs.
Mustafizur Rahman returned three for 24 and Mossadek completed a fine day with three for 29.
