SCJP 5.0 exam timings have been increased to 3 hrs 30 minutes (it is more than sufficient). The cost of exam is also reduced. I paid 6000 INR (approximately $153). In fact, the person at Prometric Centre (Hyderabad, India) told us that SUN was giving the vouchers for 5000 INR (approximately $128) in November'07
I cleared SCJP last week with score of 84%. I will share the tips for preparation and for actual exam in the SCJP results forum.
all the best to all the SCJP aspirants , you can do it
