Making full-length GMAT tests with GMATClub questions

I don't think, it would be a very good strategy to download pdf and combine the two.

The level of the questions in GMAT is always varying i.e. you get Difficult questions after easy ones and some easy after difficult ones as per GMAT Algorithm.

The ideal way of making test would be to copy one questions at a time randomly
- from one topic (you may use filter for this)
- from one difficulty level and keep increasing the difficulty level
- from PS in one file and from DS in other file

Copy about 19-20 Question of PS in one file and 18-17 questions of DS in other file (Approximate breakup of no. of questions in real GMAT as per feedback of students)
Take questions from topics as mentioned below
- Number Properties (about 7-8 questions) both PS and DS type
- Geometry (About 3-4 questions) both PS and DS but primarily PS
- Co-ordinate Geometry (About 1-2 questions) both PS and DS but primarily PS
- Inequality (About 2-3 question) both PS and DS but primarily DS
- Other topics one question

Combine the questions to make one test of 37 questions...
