mocks

was randomly surfing on the web and found out that career launcher has already launched their mock sets— 20, 30 and 40 mock options.

they have a fee waiver thing going on, so their 40 mocks set is available for around 9.5k. are their mocks good enough (commerce + eng + maths)?

and if so should i buy them now, considering they're cheaper, or buy them later?

1. 20 mocks set- around 5k
2. 30 mocks set- around 7.5k
3. 40 mocks set- around 9.5k

(ps: any other institution ke mocks that i should be on the lookout for?)
