FIRST OFF I AM A CERTIFIED MECHANIC AND WAS WORKING ON A FRIENDS CAR. HE HAD SOME COOLANT LEAKS ON HIS CAR AND WANTED ME TO CHECK THEM AND GIVE HIM A PRICE QUOTE ON PARTS AND LABOR. HE HAD ALREADY BOUGHT A NEW CAR FOR HIM SELF AND WANTED ME TO FIX THE LEAK SO THAT HE COULD SELL IT FOR 3,500... SO I DID I FOUND THE HEATER CORE LEAKING AND A CRACK ON THE RADIATOR... TOLD HIM THE DASH WOULD HAVE TO BE REMOVED AND RADIATOR WOULD NEED REPLACING AND IT WOULD BE AROUND 600 FOR PARTS AND LABOR AND THAT WAS A HOOK UP BECAUSE IT IS A LOT OF WORK...HE DIDN'T WANT TO SPEND THAT MUCH AND I THOUGHT WELL ILL BUY IT FOR 600.00 AS IS WITH THE LEAKS AND HE AGREED AND KINDA JUST WANTED TO GET RID OF IT AND ENJOY HIS NEW CAR. SO I BOUGHT IT AND GAVE IT TO MY MOM AS HER CAR WAS FALLING APART AND TOLD HER IT NEEDS A BIT OF WORK BUT THE CAR IS IN EXCELLENT CONDITION OTHER WISE AND WORTH ABOUT 3,500...SO I TOLD HER WHAT WAS WRONG WITH IT AND SAID BEFORE I TAKE THE DASH OUT AND STUFF I WANT TO TRY A STOP LEAK AND SEE WHAT HAPPENS. SO I DID, I RAN THE CAR LET IT WARM UP, PULLED A RADIATOR HOSE AND POURED HALF IN. LET IT IDLE FOR ABOUT 15 MIN AND DROVE IT. DON'T WANT TO JINX IT LOL BUT IT STOPPED BOTH LEAKS AND HAS NOT CLOGGED ANYTHING...SO I KINDA SAVED MY SELF A LOT OF WORK AND MONEY.. FOR THE BAD REVIEWS: FOLLOW THE DIRECTIONS! IF YOU HAVE A SMALL COOLING SYSTEM ONLY PUT HALF THE BOTTLE. HALF THE BOTTLE ISN'T ENOUGH TO CLOG A SYSTEM UNLESS ITS ALREADY FULL OF GUNK AND RUSTED.. ALSO IF YOU'RE ADDING MORE THAN YOU'RE SUPPOSED TOO OBVIOUSLY YOU CAN EXPECT UNEXPECTED RESULTS..IN CONCLUSION MY LEAK WAS FAIRLY BAD AND IT WORKED. TO PEOPLE SAYING ITS A TEMPORARY FIX AND WILL NEED TO BE REPLACED IN THE FUTURE YOU CAN SAY THAT ABOUT A BRAND NEW ENGINE/RADIATOR/HEATER CORE ETC...NOT EVERYTHING WILL LAST FOREVER BUT IF IT WORKS FOR A COUPLE YEARS OR AS LONG AS THE CAR THAN I CANT BEAT THAT...ITS LIKE PATCHING A TIRE THAT HAD A NAIL, YOU KNOW THERE WAS A HOLE IN THE TIRE AND YOU PATCHED IT TO SAVE MONEY.. THOSE PATCHES LAST AS LONG AS THE TIRE..ALL YOU'RE DOING IS PATCHING THE COOLING SYSTEM. IT BEATS BREAKING MY BACK AND SPENDING HUNDREDS OF DOLLARS...NOTE IF YOUR RADIATOR/COOLING SYSTEM IS SPILLING BUCKETS IT WILL PROBABLY NOT WORK...7.00 OF A CAN THAT CAN SAVE YOU ABOUT A THOUSAND DOLLARS FOR A COUPLE YEARS OR MORE SOUNDS PRETTY SMART. ...BUT IF YOU POOP MONEY THEN SURE REPLACE EVERYTHING. BUY A NEW CAR TOO.

I got my order in the mail today and skimmed through the book. I'm pretty sure most of the material is identical to the 2010-2011 version. The only difference between the two is that the full practice test is online for this version (you have to make an account in the Kaplan website to access the exam). I guess this will help you get used to the new format of the PCATs since everybody has to take them on the computer nowadays...but if you don't mind paying a few extra bucks for the online exam, I would recommend buying it. The reason I gave it 3 stars was because I was disappointed that nothing much has changed since the last version.

So far so good....used this software for about a month and no problems. Using the cloud helps quite a bit because updates and interaction are seamless. I particularly like the much smaller footprint and not having to continuously install updates manually. I haven't had much experience with other anti-virus programs but this one has so far accomplished everything I need.
