6 minutes

The academic content is in Arabic, as at the BAC and as in the app.

What the syllabus expects from you

  • Contrast connectors (whereas/while/on the other hand/however) between planets/objects

The method

  1. Locate the two contrasted facts first, then pick the connector that fits the sentence position

The common mistakes

  • 'however' used mid-clause like a coordinating conjunction (comma splice)

From the lesson

Mercury is the planet closest to the Sun. Neptune is the planet farthest from the Sun. These two facts do not agree with each other at all.

The vocabulary

  • whereas (في حين أن)
  • on the other hand (من ناحية أخرى)

What is not on the syllabus

  • Describing similarities/differences (treated separately, next concept)
