There are so many test series in the market for GS Mains that there tends to be lot of confusion at times. Vision ias, chronicle ias, synergy, vajiram etc........ I have experience of taking Vision ias test series and my experience was--
1. they are good, structured and flexible
2. checking was very delayed last year, some copies took even 20 days
3. however because of flexibility they offer, i procastinated and didnt write many tests, waste of money.
4. couldn't go for any test discussions as i didnt have time to specially travel 2 hour to and from rajinder nagar.
what has been your experience friends? which test series you recommend and why? people who have written test series before, have you given all their tests on time?
