and find that with the exception of (1) Ben Nevis, all of them are wrong!
(assuming that the listing 1 - 10 implies that the mountains listed are the ten highest in descending order of height). Aonach Mor is shown in the list, but should be at number 8 rather than number 2.
The correct list is
1 Ben Nevis 1344m (4409ft)
2 Ben Macdui 1309m (4295ft)
3 Braeriach 1296m (4252ft)
4 Cairn Toul 1291m (4236ft)
5 Sgor an Lochain Uaine (The Angel's Peak) 1258m (4127ft)
6 Cairn Gorm 1245m (4081ft)
7 Aonach Beag 1234m (4049ft)
8 Aonach Mor 1221m (4006ft)
9 Carn Mor Dearg 1220m (4003ft)
10 Ben Lawers 1214m (3983ft)
